A sample of five measurements, randomly selected from a normally distributed population, resulted in the following summary statistics: x = 4.4, s = 1.4. Complete parts a through c. a. Test the null hypothesis that the mean of the population is 6 against the alternative hypothesis, u <6. Use a = 0.10. If a = 0.10, find the rejection region for the test. Choose the correct answer below. O A. t>1.533 O B. t< -2.132 or t>2.132 O C. t>2.132 D. t< - 1.533 O E. t< -2.132 OF. t< -1.533 or t> 1.533 Calculate the value of the test statistic. t= -2.55 (Round to two decimal places as needed.) Make the appropriate conclusion. Choose the correct answer below. O A. Do not reject Ho. There is sufficient evidence at the a = 0.10 level of significance to conclude that the true mean of the population is less than 6. O B. Do not reject Ho. There is insufficient evidence at the a = 0.10 level of significance to conclude that the true mean of the population is less than 6. CC. Reject Ho. There is sufficient evidence at the a = 0.10 level of significance to conclude that the true mean of the population is less than 6. O D. Reject Ho. There is insufficient evidence at the a = 0.10 level of significance to conclude that the true mean of the population is less than 6. b. Test the null hypothesis that the mean of the population is 6 against the alternative hypothesis, µ # 6. Use a = 0.10.
