A researcher performed an experiment with two groups. She found the difference of the means for each group. Then
she combined the groups, chose two new groups, and found the difference between the means of those groups. She
repeated this process 200 times. The normal distribution of the difference in the means she found is given below. How
great would the difference in means between the first two groups have to be in order to be considered significant?
At least 8
O At least 10
At least 9
At least 7
Answers
Answer:
Step-by-step explanation:
To determine the significance level for the difference in means between the first two groups, we need to refer to the provided normal distribution. However, you haven't provided the details or parameters of the normal distribution, such as the mean and standard deviation. Without this information, it is not possible to determine the exact significance level required.
In hypothesis testing, the significance level, typically denoted as α (alpha), is chosen by the researcher before conducting the experiment. It represents the threshold at which the researcher considers the results to be statistically significant. Commonly used significance levels are 0.05 (5%) or 0.01 (1%).
Please provide the necessary parameters or more information about the normal distribution to determine the specific significance level for the difference in means between the first two groups.

The dot plot shows the number of televisions owned by the families in a neighborhood
Answers
The most appropriate measure of center for the given dot plot is the median, which is 3. The interquartile range is 3, indicating 50% of the data lies between 1 and 4.
The given dot plot shows the number of televisions owned by the families in a neighborhood. There are different measures of central tendency and variation that can be used to describe the data set. The most appropriate measure of center for this data set is the median, which is the middle value when the data is arranged in ascending or descending order.
This is because the data is not normally distributed and there are outliers in the data set.
The median value is 3, which is the middle value when the data is arranged in ascending order. The median is a better measure of center for this data set because it is not affected by outliers, unlike the mean, which can be skewed by extreme values.
The appropriate measure of variation for this data set is the interquartile range (IQR). This is because the data set is not normally distributed and there are outliers present. The IQR is the range between the 25th and 75th percentile of the data set. The IQR is 3, which indicates that 50% of the data lies between 1 and 4.
In summary, the median value of televisions owned by families in the neighborhood is 3, which is a better measure of center because it is not affected by outliers. The interquartile range is 3, which indicates that 50% of the data lies between 1 and 4.

Bryce have worked 27 and 30 minutes in september.
Because Bryce did 7/8 hours every day for 20 days,
7/8 hours is 52.5 minutes.
so then times 20, you will get 1050 minutes.
Then divided by 60(minutes per hour) you will get 17.5 hours,
which means she did 17 hours and 30 minutes in the first 20 days,
then you plus the last 1 hour per day for 10 days,
you will get 10 hours plus 17 hours and 30 minutes.

Vildia is using 60 cards to set up a card game she wants to make an array with the same numbers of cards in each row what are all the different ways vildia could arrange the cards describe all the different ways
Answers
The amount of cards in each row is a factor of 60 in each scenario, ensuring that Vildia will utilize all 60 cards and that there will be an equal number of cards in each row.
What is combination?In mathematics, a combination is a way of selecting a subset of items from a larger set, where the order of the selected items does not matter. A combination is different from a permutation, which is a way of selecting a subset of items from a larger set, where the order of the selected items does matter.
Here,
If Vildia wants to set up a card game using 60 cards and wants to make an array with the same number of cards in each row, she could arrange the cards in the following ways:
1 x 60: In this case, Vildia would arrange all 60 cards in a single row.
2 x 30: In this case, Vildia would arrange the cards in two rows, each containing 30 cards.
3 x 20: In this case, Vildia would arrange the cards in three rows, each containing 20 cards.
4 x 15: In this case, Vildia would arrange the cards in four rows, each containing 15 cards.
5 x 12: In this case, Vildia would arrange the cards in five rows, each containing 12 cards.
6 x 10: In this case, Vildia would arrange the cards in six rows, each containing 10 cards.
10 x 6: In this case, Vildia would arrange the cards in ten rows, each containing 6 cards.
12 x 5: In this case, Vildia would arrange the cards in twelve rows, each containing 5 cards.
15 x 4: In this case, Vildia would arrange the cards in fifteen rows, each containing 4 cards.
20 x 3: In this case, Vildia would arrange the cards in twenty rows, each containing 3 cards.
30 x 2: In this case, Vildia would arrange the cards in thirty rows, each containing 2 cards.
60 x 1: In this case, Vildia would arrange all 60 cards in a single column.
Note that in each case, the number of cards in each row is a factor of 60, which ensures that Vildia will use all 60 cards and that there will be an equal number of cards in each row.

The surface area of the prisms are

What is surface area?The area occupied by a three-dimensional object by its outer surface is called the surface area.
A prism is a solid shape that is bound on all its sides by plane faces.
The surface area of prism is expressed as;
SA = 2B +pH
where B is the base area , p is the perimeter and h is the height.
1. SA = 2B +ph
B = 1/2 × 6 × 8
= 24 m²
p = 6+8+10 = 24m
h = 12m
SA = 2 × 24 + 24 × 12
= 48 + 288
= 336 cm²
2. SA = 2( 3× 2) + 3× 7)+ 2 × 7)
= 2( 6+21+14)
= 2( 41)
= 82 m²
3. SA = 2πr( r +h)

The function A = 82.3e-0.002t models the population of Germany, A, in millions, t years after 2003.
(i) What was the population of Germany in 2003 ?
(ir) Is the population of Germany increasing or decreasing? Explain.
(i) In which year will the population of Germany be 81.5 million?
Answers
The population of Germany will be 81.5 million in the year 2003 + 6.24 = 2009.24, or approximately 2009.
what is function A(t) ?
Function A(t) is a mathematical expression that defines the value of a variable A in terms of the input variable t. It represents a relationship between two or more quantities.In the given problem, A(t) refers to the population of Germany in millions, t years after 2003. The specific function is A(t) = 82.3e^(-0.002t), where A(t) represents the population of Germany in millions and t represents the number of years after 2003.
According to the question:
(i) We know that the function models the population of Germany, A, in millions, t years after 2003. So, if we substitute t = 0 (i.e., in 2003) in the function, we can find the population of Germany in 2003.
\(A = 82.3e^{-0.002*0}\)
\(A = 82.3e^0\)
A = 82.3
Therefore, the population of Germany in 2003 was 82.3 million.
(ii) The function has a negative exponential term, which means that the value of A decreases as t increases. So, the population of Germany is decreasing over time.
(iii) We can solve the equation 82.3e^(-0.002t) = 81.5 to find the year when the population of Germany will be 81.5 million.
Dividing both sides by 82.3, we get:
\(e^{-0.002t} = 81.5/82.3\)
Taking the natural logarithm (ln) of both sides, we get:-0.002t = ln(81.5/82.3)Solving for t, we get:
t = -ln(81.5/82.3)/0.002t ≈ 6.24
Therefore, the population of Germany will be 81.5 million in the year 2003 + 6.24 = 2009.24, or approximately 2009.

Remember that an x-intercept is a point in which the line touches the x-axis (the horizontal line). And, the y-intercept is a point in which the line touches the y-axis (the vertical/up and down line)

The coordinate of the y-intercept is (0,1)
The coordinate of the x-intercept is (3,0)
For B)
The coordinate of the y-intercept is (0,0)
The coordinate of the x-intercept is (0,0) !
