Question

The sample of six measurements shown below was randomly selected from a normally distributed population. Complete parts a throughc 1,3, 1, 5, 1,2 a. Test the null hypothesis that the mean of the population is 3 against the alternative hypothesis, 3. Use a 0.10. If a = 0.10, find the rejection region for the test. Choose the correct answer below O A. t 2.015 or t> 2.015 O C. t-2015 O E. t1476 O B. t-1.476 O D. t 1.476 or t> 1.476 O F t2.015 Calculate the value of the test statistic. (Round to two decimal places as needed.) Make the appropriate conclusion. Choose the correct answer below. O A. 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 3. O B. Reject Ho There is insufficient evidence at thea= 0.10 level of significance to conclude that the true mean of the population is less than 3. O C. Do not reject H There is sufficient evidence at the a 0.10 level of significance to conclude that the true mean of the population is less than 3. . .. .. O D. Do not reject H There is insufficient evidence at the 0.10 level of significance conclude that the true mean of the population is less than 3. b. Test the null hypothesis that the mean of the population is 3 against the alternative hypothesis, u#3. Use 0.10. If a 0.10, find the rejection region for the test. Choose the correct answer below. O B. t-2015 O D. t 2.015 O F. t1.476 O A. t 1.476 O C. t 1.476 ort> 1.476 Q E. t 2.015 ort> 2.015 Calculate the value of the test statistic. Round to two decimal places as needed) Make the appropriate conclusion. Choose the correct answer below. O A. Reject H There is sufficient evidence at the a = 0.10 level of significance to conclude that the true mean of the population is not 3. O B. Do not reject H There is insufficient evidence at the a 0.10 level of significance to conclude that the true mean of the population is not 3. O C. Do not reject H. There is sufficient evidence at the a 0.10 level of significance to conclude that the true mean of the population is not 3
