Question

Luoston help The test statistic of z = 2.12 is obtained when testing the claim that p#0.688. a. Identify the hypothesis test as being two-tailed, left-tailed, or right-tailed. b. Find the P-value. c. Using a significance level of a = 0.01, should we reject Hy or should we fail to reject Ho? Click here to view page 1 of the standard normal distribution table. Click here to view page 2 of the standard normal distribution table a. This is a test b. P-value - (Round to three decimal places as needed.) c. Choose the correct conclusion below. O A Reject Ho. There is not sufficient evidence to support the claim that p*0.688. OB. Reject Ho. There is sufficient evidence to support the claim that p*0.688. OC. Fail to reject Ho. There is not sufficient evidence to support the claim that p#0.688. OD. Fail to reject Hy. There is sufficient evidence to support the claim that p#0.688.

Answer 1

Given, Test statistic =2= 2.12 claim : P 20.688 ay This is two-tailed test by p-value = 2P12>2.12). = 2 [1- P(Z<2.12)] using 2-table, we gel = 2/1-0.98307 P-value = 0.034 =10.034 p-value (0.034) is greater than x=0.01 c) conclusima [cy Fail to reject Ho. There is not sufficient evidence to support the claim that PE 0.688.
