A sample of size n=45 is drawn, and x =20. The population standard deviation is o =7. Espanol (a) Compute the value of the test statistic z. (b) Is Ho rejected at the a=0.10 level? (c) Is Ho rejected at the a=0.01 level? OO Part: 0 / 3 Part 1 of 3 (a) Compute the value of the test statistic. Round the answer to at least two decimal places. Z = 1.92 5 X 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. Critical Values for a=0.10 Critical Values for a =0.01 O Left-tailed Right-tailed 1.282 2.326 O Two-tailed and and X Part: 2 / 3 Part 3 of 3 Determine whether to reject Ho . H at the (b) Since the test statistic, z= 1.92, is |in the critical region, we reject a=0.10 level. H at the (c) Since the test statistic, z= 1.92, |Select |in the critical region, we do not reject a=0.01 level. Submit Assignment Continue
