Harry's Hamburgers claims that the residents of Harryville eat at the hamburger chain an average of exactly 18 times per year. You took a sample of 48 residents of Harryville and found that the sample mean was 17. The sample standard deviation was 4.5. You want to test to see if Harry's claim can be disputed with a significance level of 0.05. For each number in the problem, give the appropriate mathematical symbol associated with that number: 18 = Use the Margin of Error to calculate a confidence interval. State the confidence interval below as a compete sentence, using the format shown in Module 12.90. Round your numbers to one decimal point.
