Refer to previous question. At a .05 level of significance, it can be concluded that the proportion of the population in favor of candidate A is:
Answers
Using the z-distribution, it is found that since the test statistic is less than the critical value for the right-tailed test, it is found that it can be concluded that the proportion of the population in favor of candidate A is not significantly greater than 0.75.
At the null hypothesis, it is tested if the proportion is not significantly more than 75%, that is:
\(H_0: p \leq 0.75\)
At the alternative hypothesis, it is tested if the proportion is significantly more than 75%, that is:
\(H_1: p > 0.75\)
The test statistic is given by:
\(z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}\)
In which:
\(\overline{p}\) is the sample proportion. p is the proportion tested at the null hypothesis. n is the sample size.In the sample, 80 out of 100 people favored candidate A, hence, the parameters are:
\(n = 100, \overline{p} = \frac{80}{100} = 0.8, p = 0.75\)
Hence:
\(z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}\)
\(z = \frac{0.8 - 0.75}{\sqrt{\frac{0.75(0.25)}{100}}}\)
\(z = 1.15\)
The critical value for a right-tailed test, as we are testing if the proportion is greater than a value, is \(z^{\ast} = 1.645\).
Since the test statistic is less than the critical value for the right-tailed test, it is found that it can be concluded that the proportion of the population in favor of candidate A is not significantly greater than 0.75.

Answers
According to the question we have the 99% UCB on the mean time of the race is 223.
The formula for finding the upper confidence bound (UCB) is UCB = Mean + (Zα/2)(σ/√n), where Mean is the sample mean, Zα/2 is the z-score for the desired level of confidence, σ is the population standard deviation (which is not given, so we'll use the sample standard deviation instead), and n is the sample size.
We are given the sample of times as follows:137, 143, 153, 162, 168, 176, 190, 192, 196, 203, 218, 223, 236, 243, 252, 269, 271, 276, 283, 287.
We'll need to calculate the sample mean and standard deviation before we can find the UCB. Using a calculator, we get: mean ≈ 207.65s ≈ 48.41 Next, we'll use a table or calculator to find the z-score for a 99% confidence interval, which is Zα/2 = 2.576.
Now we can plug in the values we know to get the UCB:UCB = mean + (Zα/2)(σ/√n)UCB ≈ 207.65 + (2.576)(48.41/√20)UCB ≈ 223.02 .Therefore, the 99% UCB on the mean time of the race is 223.

Answers
A sampling distribution is the probability distribution of a statistic for all random samples of n observations from a population. The term "sampling distribution" refers to the probability distribution of a statistic, such as the mean or standard deviation, that arises from random sampling of a fixed-sized sample from a population.
It is essential to understand this concept because it allows us to make inferences about the population parameter using information from the sample statistic. The standard deviation of the sampling distribution is known as the standard error of the statistic, and it measures how much the statistic varies across all possible samples of the same size from the population. In short, the sampling distribution is a theoretical distribution that helps us to understand the properties of the statistic and make inferences about the population parameter based on sample data.

Find all points of inflection on the graph of the function f(x)= (1/3)x^3+9x^2
Answers
To find the point of inflection on the graph of f(x) = (1/3)x^3 + 9x^2, we need to determine the values of x where the concavity changes. the point of inflection is at x = -9.
To find the points of inflection, we first need to find the second derivative of the function f(x).
Taking the derivative of f(x) with respect to x, we get:
f'(x) = x^2 + 18x
Next, we take the derivative of f'(x) to find the second derivative:
f''(x) = 2x + 18
To find the points of inflection, we set the second derivative equal to zero and solve for x:
2x + 18 = 0
Solving this equation, we find that x = -9.
Therefore, the point of inflection on the graph of f(x) = (1/3)x^3 + 9x^2 is at x = -9.

Incorrect. We are 95% confident that the interval from 26.2 and 27.4 captures the BMI of all young American women.
Correct. The interval states that the mean BMI of young American women is between 26.2 and 274, so the mean cannot be 28. Incorrect. We are 95%confident that the interval from 26.2 and 274 captures the true mean BMI of all young American women. Incorrect. If we take many samples, the population mean BMI will be between 26.2 and 27.4 in about 95% of those samples.
Answers
Incorrect. We are 95% confident that the interval from 26.2 and 27.4 captures the BMI of all young American women is the correct interpretation of the confidence interval.
A 95% confidence interval is a range of values that we can be 95% sure contains the true mean of the population. The 95% confidence interval for the mean body mass index (BMI) of young American women is 26.8 ± 0.6.
This means that we are 95% confident that the true mean BMI of young American women is between 26.2 and 27.4.
Consequently, the statement, "The mean BMI of young American women cannot be 28" is incorrect as the confidence interval does not include the value 28.
However, this does not imply that the true mean BMI of young American women cannot be 28.
A confidence interval is a statistical range that provides an estimate of the possible values for an unknown population parameter, such as a mean or proportion, based on a sample from that population. It provides a range of values within which the true population parameter is likely to fall, along with a specified level of confidence.

to compute its height h to be 10 centimeters.
The base of the second prism has the same side length, but has 5 times the volume. What is its height?
Answers
The height of the second square base prism is 50 cm.
How to find volume of a square base prism?The volume of the first square base prism is represented as follows:
v = ha²
where
h = heighta = side length of the baseTherefore, the height of the prism is 10 cm.
v = 10a²
Hence, the volume of the initial prism is 5 times the volume. Therefore,
v = 5(10a²)
v = 50a²
Therefore,
50a² = ha²
divide both sides by a²
50a² / a² = ha² / a²
50 = h
h = 50 cm
Therefore, the height of the second square base prism is 50 cm.
