A recent survey reported that small businesses spend 29 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 29 hours a week on marketing. The chamber conducts a survey of 98 small businesses within their state and finds that the average amount of time spent on marketing is 27.6 hours a week. Assuming that the population standard deviation is 8.1 hours, is there sufficient evidence to support the chamber of commerce's claim at the 0.01 level of significance? Step 2 of 3: Compute the value of the test statistic. Round your answer to two decimal places.
