esis Question 4, Instructor- created question HW Score: 27.41%, 12.33 of 45 points Points: 0 of 7 Save A simple random sample of 44 adults is obtained from a normally distributed population, and each person's red blood cell count (in cells per microliter) is measured. The sample mean is 5.28 and the sample standard deviation is 0.54. Use a 0.05 significance level and the given calculator display to test the claim that the sample is from a population with a mean less than 5.4, which is a value often used for the upper limit of the range of normal values. What do the results suggest about the sample group? T-Test <5.4 t = -1.474055462 p = 0.0738753053 x=5.28 Sx = 0.54 n=44 What are the null and alternative hypotheses? A. Ho: =5.4 H>5.4 C. Ho: H=5.4 <5.4 Identify the test statistic. (Round to three decimal places as needed.) Identify the P-value. (Round to four decimal places as needed.) B. Ho: <5.4 H = 5.4 D. Ho: =5.4 H: 5.4 State the final conclusion that addresses the original claim. Use either the traditional method or the P-value method for testing hypotheses. Choose the correct answer below. A. Reject Ho. There is sufficient evidence to support the claim that the sample is from a population with a mean less than 5.4. B. Fail to reject Ho. There is not sufficient evidence to support the claim that the sample is from a population with a mean less than 5.4. C. Fail to reject Ho. There is sufficient evidence to support the claim that the sample is from a population with a mean less than 5.4. D. Reject Ho. There is not sufficient evidence to support the claim that the sample is from a population with a mean less than 5.4. What do the results suggest about the sample group? A. There is not enough evidence to conclude that the sample is from a population with a mean less than 5.4, so it is unlikely that the population has counts that are too high. B. There is enough evidence to conclude that the sample is from a population with a mean less than 5.4, so it is unlikely that the population has counts that are too high. C. There is enough evidence to conclude that the sample is from a population with a mean less than 5.4, so it is possible that the population has counts that are too high. D. There is not enough evidence to conclude that the sample is from a population with a mean less than 5.4, so it is possible that the population has counts that are too high. esis Question 4, Instructor- created question HW Score: 27.41%, 12.33 of 45 points Points: 0 of 7 Save A simple random sample of 44 adults is obtained from a normally distributed population, and each person's red blood cell count (in cells per microliter) is measured.
