The website Web MD claims that more than 88% of the women wear the wrong size shoe. He bases this on a sample of women whose shoe sizes he has checked. Assume that a hypothesis test of the claim has already been conducted at the 0.05 level of significance. The following results were obtained: test statisticz= 1.37 and p-value = 0.0851. What can you conclude? Hint: Set-up Ho and H, first and read the answer choices carefully! O A. Reject H,. There is sufficient evidence to support the claim that more than 88% of women wear the wrong size shoe. O B. Accept Ho. There is sufficient evidence to support the claim that more than 88% of women wear the wrong size shoe. O C. Do not reject Ho. There is not sufficient evidence to support the claim that more than 88% of women wear the wrong size shoe O D. Reject Ho.
