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 = Now we are going to redo the question using the confidence interval approach. The first step is to calculate the Margin of Error. Give that number below. Round your answer to one decimal point.
