Check My Work (2 remaining CCN and ActMedia provided a television channel targeted to individuals waiting in supermarket checkout lines. The channel showed news, short features, and advertisements. The length of the program was based on the assumption that the population mean time a shopper stands in a supermarket checkout line is 8.1 minutes. A sample of actual waiting times will be used to test this assumption and determine whether actual mean waiting time differs from this standard. a. Formulate the hypotheses for this application. Select your answer - 8.1 Ha P Select your answer - 8.1 b. A sample of 100 shoppers showed a sample mean waiting time of 8.9 minutes. Assume a population standard deviation of a = 2.8 minutes. What is the p-value? z value (to 2 decimals) p-value (to 4 decimals) C. At a = 0,.02, what is your conclusion?
