A test is made of H.: = 18 versus H: A > 18. A sample of size n= 45 is drawn, and I = 20. The population standard deviation is 5 - 7. (a) Compute the value of the test statistic z. (b) Is I rejected at the a= 0.10 level? (c) Is He rejected at the a = 0.01 level? Part 1 of 3 a) Compute the value of the test statistic. Round the answer to at least two decimal places. 192 Part: 1 / 3 Part 2 of 3 Choose the correct type of hypothesis test. Then find the critical values for a= 0.10 and a= 0.01. Round your answers to three decimal places, if necessary.
