Extracted text: You are a lead certified public accountant (CPA) working for the American Institute of Certified Tax Planners, an organization that analyzes tax policy and planning across the US. Your boss, Penny Patrol, has sent you the following email: Lead CPA, As you know, we are interested in comparing the average number of hours worked by CPAS in states with flat income tax rates versus CPAS in the US as a whole. The average US CPA works 60 hours per week during tax season. The results from our survey indicate that out of our sample of 150 CPAS in flat tax rate states, the average is 55 hours per week during tax season. Based upon past studies, we are assuming a population standard deviation of 27.4. Do CPAS in states that have flat state income tax rates work fewer hours per week during tax season compared to the US average? Please use a 95% confidence level in your analysis. Also, since what we found will be written up in a technical report, please formally state the null and alternative hypotheses, report either the test statistic or p-value, and explain why based upon your analysis you either reject or fail to reject your null һурothesis. Thanks, Penny Patrol
