According to an article published in the Journal of Consumer Psychology(2003, 13(3), pp. 278-288), children in the United States account for $36 billion in sales annually. When their indirect influence over product decisions from stereos to vacations is considered, the total economic spending affected by children in the United States is $290 billion. The authors estimated that by age 10, a child makes an average of more than five trips a week to a store. Suppose that you want to test that children in your city average more than 5 trips a week to a store. A sample of 25 children resulted in a mean number of trips to a store of 5.47 with a standard deviation of 1.4.

Use the 0.05 level of significance and p-value approach. Is there evidence that the population mean number of trips to a store is greater than 5 times a week?
