A test is made of HO: u=20 versus H1: p>20. A sample of size n=53 is drawn, and 1: =22. The population standard deviation is o = 5. (a) Compute the value of the test statistic z. (b) Is H0 rejected at the (1:0.05 level? (c) Is H0 rejected at the a=0.10 level? (a) Compute the value of the test statistic. Round the answer to at least two decimal places. Choose the correct type of hypothesis test. Then find the critical values for 0i=0.05 and u=0.10. Round your answers to three decimal places, if necessary. 0 Left-tailed D E] O Right-tailed E] E] O Two-tailed D and E] E] and D
