The test statistic of z = 2.34 is obtained when testing the claim that p # 0.879. a. Identify the hypothesis test as being two-tailed, left-tailed, or right-tailed. b. Find the P-value. c. Using a significance level of a = 0.05, should we reject Ho or should we fail to reject Ho? Click here to view page 1 of the standard normal distribution table. Click here to view page 2 of the standard normal distribution table. a. This is a test. (Round to three decimal places as needed.) b. P-value = c. Choose the correct conclusion below. Fail to reject Ho. There is not sufficient evidence to support the claim that p+ 0.879. A. Fail to reject Ho. There is sufficient evidence to support the claim that p +0.879. B. C. Reject Ho. There is sufficient evidence to support the claim that p + 0.879. D. Reject Ho. There is not sufficient evidence to support the claim that p#0.879.

Is memory ability before a meal the same as after a meal? Ten people were given memory tests before their meal and then again after their meal. The data is shown below. A higher score indicates a better memory ability. Ho: Select an answer H₁: Select an answer ✓ Before a Meal After a Meal Assume a Normal distribution. What can be concluded at the the a = 0.01 level of significance? For this study, we should use Select an answer a. The null and alternative hypotheses would be: b. The test statistic ? ✓ = Score on the Memory Test 67 44 71 77 63 76 53 50 71 82 76 54 71 86 75 88 58 49 89 83 Select an answer Select an answer V c. The p-value d. The p-value is ? ✓ a e. Based on this, we should f. Thus, the final conclusion is that ... Select an answer Select an answer (please enter a decimal) (Please enter a decimal) (please show your answer to 3 decimal places.) (Please show your answer to 4 decimal places.) Select an answer the null hypothesis.

Given in the table are the BMI statistics for random samples of men and women. Assume that the two samples are independent simple random samples selected from normally distributed populations, and do not assume that the population standard deviations are equal. Complete parts (a) and (b) below. Use a 0.01 significance level for both parts. a. Test the claim that males and females have the same mean body mass index (BMI). What are the null and alternative hypotheses? OA. Ho: H=H H₁: Hy > H₂ ỌC. Ho: H=H2 H₁: H₁ H₂ The test statistic, t, is. (Round to two decimal places as needed.) The P-value is (Round to three decimal places as needed.) State the conclusion for the test. -C OB. Ho: ₁2/₂ H₁ H₁ H₂ OD. Ho. Hy#t H₁: H₁ H₂ O A. Fail to reject the null hypothesis. There is sufficient evidence to warrant rejection of the claim that men and women have the same mean BMI. O B. Fail to reject the null hypothesis. There is not sufficient evidence to warrant rejection of the claim that men and women…
