A recent survey reported that small businesses spend 24 hours a week marketing their business. A local chamber of commerce claims that small businesses in their area are not growing because these businesses are spending less than 24 hours a week on marketing. The chamber conducts a survey of 80 small businesses within their state and finds that the average amount of time spent on marketing is 23.0 hours a week. Assuming that the population standard deviation is 5.4 hours, is there sufficient evidence to support the chamber of commerce’s claim at the 0.02 level of significance?   Step 2 of 3 : Compute the value of the test statistic. Round your answer to two decimal places.
