OHP<0.62 H:p2 0.62 W O Ho: PS 0.62 H:P >0.62 O Ho: PZ 0.62 H₂:p<0.62 O Ho:p> 0.62 H:ps 0.62 Ho: P = 0.62 H:D 0.62 (b) If a sample of 100 shoppers showed 51 stating that the supermarket brand was as good as the national brand, what is the p-value? Find the value of the test statistic. (Round your answer to two decimal places.) Find the p-value. (Round your answer to four decimal places.) p-value= x (c) At a = 0.05, what is your conclusion? Do not reject Hg. There is insufficient evidence to conclude that the percentage of supermarket shoppers who believe that supermarket ketchup is as good as the national brand ketchup is less than 62%. O Reject Ho.
