A recent survey reported that small businesses spend 28 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 28 hours a week on marketing. The chamber conducts a survey of 62 small businesses within their state and finds that the average amount of time spent on marketing is 25.9 hours a week. Assuming that the population standard deviation is 7.0 hours, is there sufficient evidence to support the chamber of commerce's claim at the 0.02 level of significance? Step 1 of 3: State the null and alternative hypotheses for the test. Fill in the blank below. Ho : μ = 28 Hap 28
