A recent survey reported that small businesses spend 22
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 22
hours a week on marketing. The chamber conducts a survey of 72
small businesses within their state and finds that the average amount of time spent on marketing is 20.9
hours a week. Assuming that the population standard deviation is 5.1
hours, is there sufficient evidence to support the chamber of commerce’s claim at the 0.05
level of significance?
Step 2 of 3 : Compute the value of the test statistic. Round your answer to two decimal places.
