The hypothesis are given as follows:
Null hypothesis: \(H_0: \pi_1 = \pi_2\)Alternative hypothesis: \(H_1: \pi_1 \neq \pi_2\)The test statistic is given as follows:
z = 38.92.
The critical value is given as follows:
z = 1.96.
The conclusion is given as follows:
Since the test statistic is greater than the critical value, reject the null hypothesis. There is sufficient evidence to conclude that there is a significant difference between the proportion of Superbanked and the Unbanked with respect to using credit cards.
The p-value is of: 0.
The p-value is the probability that in a random sample of 1,000 Superbanked consumers and 1,000 Unbanked customers, the difference between the proportions of Superbanked and Unbanked customers is at least 0.65.
What are the hypothesis tested?At the null hypothesis, it is tested if the hypothesis are equal, that is:
\(H_0: \pi_1 = \pi_2\)
At the alternative hypothesis, it is tested if they are different, that is:
\(H_1: \pi_1 \neq \pi_2\)
We are testing if the two proportions are different, hence we have a two-tailed test, using the z-distribution, with a significance level of 0.05, and the critical value is given as follows:
z = 1.96.
Then the decision rule is given as follows:
|z| < 1.96: do not reject the null hypothesis.|z| > 1.96: reject the null hypothesis.How to obtain the test statistic and p-value?To obtain the test statistic, we need to obtain the proportion and the standard error for each sample, as follows:
\(\pi_1 = 0.89, s_1 = \sqrt{\frac{0.89(0.11)}{1000}} = 0.0099\)\(\pi_2 = 0.24, s_1 = \sqrt{\frac{0.24(0.76)}{1000}} = 0.0135\)Hence, for the distribution of differences, the mean and the standard error are given as follows:
p = 0.89 - 0.24 = 0.65.s = square root (0.0099² + 0.0135²) = 0.0167.The test statistic is given by the division of the mean by the standard error, hence:
z = p/s = 0.65/0.0167 = 38.92.
Using a z-distribution calculator, with a two-tailed test and z = 38.92, the p-value is of 0.

clarify why the Bill of rights provides for section 36 which sets limits to the exercise of all the rights in south Africa
Answer:
The purpose of Section 36 of the Bill of Rights is to ensure that the exercise of individual rights is balanced against the greater interests of society, and that any limitations on those rights are reasonable and justifiable in a democratic society.
Explanation:
Section 36 of the South African Constitution is known as the "Limitation Clause," and it sets limits on the exercise of all rights enshrined in the Bill of Rights. The reason for this clause is to ensure that the exercise of individual rights does not unjustifiably infringe upon the rights of others or the public interest.
The Bill of Rights in the South African Constitution is considered one of the most progressive in the world, as it guarantees a range of civil, political, economic, social, and cultural rights to all citizens. However, it also recognizes that there may be circumstances where the exercise of those rights may need to be limited in the interests of society as a whole.
Section 36 allows for the limitation of rights in certain situations, but only if the limitation is reasonable and justifiable in an open and democratic society based on human dignity, equality, and freedom. This means that any limitation on a right must be for a legitimate purpose and must be proportional to the importance of that purpose.
For example, the right to freedom of expression may be limited if that expression promotes hate speech or incites violence. The right to property may be limited if it is necessary to promote land reform or address historical injustices. However, any limitation must be necessary, reasonable, and justifiable in a democratic society.
In summary, the purpose of Section 36 of the Bill of Rights is to ensure that the exercise of individual rights is balanced against the greater interests of society, and that any limitations on those rights are reasonable and justifiable in a democratic society.
Answer:
In addition, the Constitution provides a General Limitation Clause at Section 36, which provides for all rights in the Bill of Rights to be limited in terms of law of general application and that "limitations must be reasonable and justifiable in an open and democratic society based on human dignity, equality, and ...

What are five facts about the Rural Area/Poverty Class, that stood out for you, during the period?
Urgent!!!!
1 Many people in the rural areas worked as agricultural laborers and lived in poverty with large families crammed into small cottages.
2 The rural poor had limited access to healthcare and education, which resulted in high infant mortality rates and low literacy rates.
3 The living conditions in the rural areas were often unsanitary and unhygienic, with inadequate sewage and drainage systems.
4 Many rural families supplemented their income by taking in lodgers or performing piecework such as lace making or straw plaiting.
5 The workhouses were seen as a last resort for the rural poor, who would have to surrender their independence and live in harsh conditions in exchange for food and shelter.

what is the vertex of x^2 + 4x - 12
Answer:
\((-2, -16)\\\)
Explanation:
The vertex of a quadratic function which gets plotted as a parabola is either the minimum or maximum (x, y) value of that function.
The following rule applies to finding the x value of the vertex
\(\mathrm{The\:vertex\:of\:an\:up-down\:facing\:parabola\:of\:the\:form}\:\\y=ax^2+bx+c\:\mathrm{is}\:x_v=-\dfrac{b}{2a}\)
The equation is
\(y=x^2+4x-12\)
\(\textrm {Here }\\a = 1, b = 4, c= -12\\\\\)
\(So\; x_v, \textrm{ the x value of the vertex } = -\dfrac{4}{2\cdot \:1} = -2\\\\\textrm {Plug this value of x into the equation to find the y-value of the vertex}\\\)
\(y_v=\left(-2\right)^2+4\left(-2\right)-12\\\\\\y_v = 4 -8 - 12 = -16\\\\\)
\(\mathrm{Therefore\:the\:parabola\:vertex\:is}\\(-2, -16)\)

One of the functions of sociology of education is the development of new social patterns (see p5 in SoE). Briefly discuss how this aim could be taught in the classroom. (3)
Teaching the aim of developing new social patterns within the context of the sociology of education requires a comprehensive and interactive approach in the classroom.
Some strategies that could be used to effectively teach this aim:
1)Introduce case studies: Presenting real-life case studies that demonstrate social patterns and their consequences can help students understand the importance of developing new social patterns.
By analyzing these cases, students can identify existing social patterns, evaluate their impacts, and brainstorm potential alternatives.
2)Encourage critical thinking: Foster critical thinking skills by engaging students in discussions and debates about current social patterns and their implications.
Encourage them to question the status quo, challenge existing norms, and explore alternative social arrangements.
This can be done through open-ended questions, group activities, and analyzing conflicting viewpoints.
3)Collaborative projects: Assigning collaborative projects that require students to propose and develop new social patterns can be an effective way to engage them in active learning.
Students can work in groups to identify social issues, research potential solutions, and create action plans for implementing new social patterns.
This hands-on approach encourages creativity, teamwork, and problem-solving skills.
4)Guest speakers and field trips: Inviting guest speakers from various fields, such as sociology, education, and community organizations, can provide students with real-world insights into the development of new social patterns.
Organizing field trips to relevant community organizations or institutions can also give students the opportunity to observe and learn from initiatives that aim to create positive social change.
5)Reflective activities: Incorporate reflective activities, such as journaling, class discussions, or personal presentations, where students can express their thoughts, insights, and personal experiences related to social patterns.
Encourage them to critically reflect on their own behaviors, attitudes, and the potential impact they can have on social patterns.

1. How long to fill a pallet? Phillip recorded how long it takes to fill a pallet in minutes [ 35, 36, 32, 42, 58, 56, 56, 35, 39, 46, 47, 34, 37 ]
2. For the numbers 13, 16, 12, 11, 8, 14, 12, and 18 Which of the following is true? Mean> median > mode. Median> mean > mode Mode > mean> median 8, 11, 12, 12, 13, 14, 16, 18
3. The numbers 7, 6, 10, 13, 7, 2, 5, 6, and x have only one mode and the mean median and mode are all equal. what is the valve of x ?
Answer:
Therefore, the missing value is x = 7.
Explanation:
1. To find the average time it takes to fill a pallet, we can calculate the mean of the recorded times.
Mean = (35 + 36 + 32 + 42 + 58 + 56 + 56 + 35 + 39 + 46 + 47 + 34 + 37) / 13
Mean = 45.5
Therefore, on average, it takes approximately 45.5 minutes to fill a pallet.
2. To determine the relationship between the mean, median, and mode, we first need to find each value.
Mean = (13 + 16 + 12 + 11 + 8 + 14 + 12 + 18) / 8
Mean = 13.5
To find the median, we need to first order the numbers from least to greatest: 8, 11, 12, 12, 13, 14, 16, 18. Since there are an even number of values, we take the average of the two middle values to find the median.
Median = (12 + 13) / 2
Median = 12.5
The mode is the value that appears most frequently, which is 12.
Now we can compare the values:
Mean > median > mode
Therefore, the correct answer is: Mean > median > mode.
3. We know that the mean, median, and mode are all equal in this set of numbers. To find the missing value, we need to first find the current mean/median/mode.
Mean = Median = Mode
We can calculate the mean by adding all the values and dividing by the total number of values:
(7 + 6 + 10 + 13 + 7 + 2 + 5 + 6 + x) / 9 = (56 + x) / 9
Since we know that the mean/median/mode are all equal, we can set this expression equal to the missing value (x):
(56 + x) / 9 = x
Multiplying both sides by 9:
56 + x = 9x
Subtracting x from both sides:
56 = 8x
Dividing both sides by 8:
x = 7
Therefore, the missing value is x = 7.

1. Which sentence can be made more readable simply by removing a phrase?
- Jefferson Avenue was crowded with loads of protestors.
-When we got home, we saw ourselves on television.
-We left the rally early because things seemed a little sketchy.
-The crowd grew quiet when the main speaker walked onstage.
Answer:
3
Explanation:
The sentence that can be made more readable simply by removing a phrase is:
- We left the rally early because things seemed a little sketchy.
The sentence can be shortened to "We left the rally early." This removes the unnecessary and vague phrase "because things seemed a little sketchy," which does not add any specific detail or clarity to the sentence.

If 7 men 5 women have applied for job and 3 applicants are randomly selected from the probability that 2 are men how many WOmen?
.
The probability of selecting 2 men and a woman is \(\frac{21}{44}\)
The sample space is made up of 7 men and 5 women. So we have a total of 12 people.
If 3 applicants are randomly selected without replacement, there will be three mutually exclusive possibilities;
\(MMW=\text{Event that a Man, then Man, then Woman is selected}\\MWM=\text{Event that a Man, then Woman, then Man is selected}\\WMM=\text{Event that a Woman, then Man, then Man is selected}\\\)
The final probability will have the form
\(P(\text{2 men and 1 woman})=P(MMW)+P(MWM)+P(WMM)\)
because the possibilities are mutually exclusive.
Computing the Probability of each possibilityEach mutually exclusive possibility is made up of dependent events. This is because when selection is done without replacement, it affects the size of the sample space.
The Probability of selecting a Man, then a Man, then a Woman is\(P(MMW)=\dfrac{7}{12}\times\dfrac{6}{11}\times\dfrac{5}{10}\\\\=\dfrac{7}{44}\)
The Probability of selecting a Man, then a Woman, then a Man is\(P(MWM)=\dfrac{7}{12}\times\dfrac{5}{11}\times\dfrac{6}{10}\\\\=\dfrac{7}{44}\)
