A city claims that the mean number of public transportation users per day is at least 4,800. A group of researchers think this is not accurate and want to show that the number of public transportation users is less than 4,800 Identify the null hypothesis, Ho, and the alternative hypothesis, Ha , in terms of the parameter μ. Select the correct answer below: O Ho: μ < 4,800; Ha: μ 24,800 Ho: u > 4,800; Ha: u K 4,800 Ho: μ 4,800; Ha: μ > 4,800 Ho: μ 24,800; Ha : μ < 4,800 O O

Assume a significance level of α=0.05 and use the given information to complete parts​ (a) and​ (b) below.   Original​ claim: The mean pulse rate​ (in beats per​ minute) of a certain group of adult males is 68 bpm. The hypothesis test results in a​ P-value of 0.0901. a. State a conclusion about the null hypothesis.​ (Reject H0 or fail to reject H0​.) Choose the correct answer below.     A. Reject H0 because the​ P-value is greater than α.   B. Fail to reject H0 because the​ P-value is greater than α.   C. Reject H0 because the​ P-value is less than or equal to α.   D. Fail to reject H0 because the​ P-value is less than or equal to α. b. Without using technical​ terms, state a final conclusion that addresses the original claim. Which of the following is the correct​ conclusion?     A. There is sufficient evidence to warrant rejection of the claim that the mean pulse rate​ (in beats per​ minute) of the group of adult males is 68 bpm.   B.…

Perform the following hypothesis test: HO: µ = 10 H1: µ  10 The sample mean is 9.55, population standard deviation of 1.5 and a sample size of 51.  Use a 5% significance level. What is the value of the test statistic? (Give your answer rounded to 2 decimals) (Be careful to make sure your + or - sign is correct)

Select the most appropriate response. It is claimed that the mean age of bus drivers in Chicago is 59.3 years. If a hypothesis test is performed, how should you interpret a decision that fails to reject the null hypothesis? Question 2 options: There is not sufficient evidence to reject the claim µ = 59.3. There is sufficient evidence to reject the claim p = 59.3. There is not sufficient evidence to support the claim p = 59.3. There is sufficient evidence to support the claim u = 59.3.

Assume a significance level of α=0.1 and use the given information to complete parts​ (a) and​ (b) below.   Original​ claim: The mean pulse rate​ (in beats per​ minute) of a certain group of adult males is 70 bpm. The hypothesis test results in a​ P-value of 0.0025. a. State a conclusion about the null hypothesis.​ (Reject H0 or fail to reject H0​.) Choose the correct answer below.     A. Fail to reject H0 because the​ P-value is less than or equal to α.   B. Reject H0 because the​ P-value is less than or equal to α.   C. Reject H0 because the​ P-value is greater than α.   D. Fail to reject H0 because the​ P-value is greater than α. b. Without using technical​ terms, state a final conclusion that addresses the original claim. Which of the following is the correct​ conclusion?     A. The mean pulse rate​ (in beats per​ minute) of the group of adult males is 70 bpm.   B. There is sufficient evidence to warrant rejection of the claim that the…
