Question

The test statistic of zs -2.78 is obtained when testing the claim that p <0.46. a. Using a significance level of a=0.01, find the critical value(s). b. Should we reject He or should we fail to reject H? 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. The critical value(s) is/are z= (Round to two decimal places as needed. Use a comma to separate answers as needed.) b. Choose the correct conclusion below. O A. Reject Ho. There is not sufficient evidence to support the claim that p < 0.46. O B. Fail to reject Ho. There is not sufficient evidence to support the claim that p<0.46. OC. Reject Ho. There is sufficient evidence to support the claim that p <0.46. OD. Fail to reject Ho There is sufficient evidence to support the claim that p<0.46. SOCCOLA

Answer 1

Ho: P = 0.46 H:P < 0.46 (left teiled Heat) Test Stalistic, Z=-278 a) Critical value, daniel Zx=Z0-01-[-2.33 (using z table] Rejection rulee Reject Ho, if Z <=2.33 /non sejection Degiron / rejection region -2.33 Ó Z b) Since the test stahistre value is in the rejection Begion So, Reject Mo, there is sufficient widence to support - the claim that P < 0.46 Correct option is fel
