If a random sample of 54 restaurants is taken and results in a sample mean of 3.3 claims, find a 95% confidence interval for the population mean.

Use the tool below to calculate your confidence interval. Choose the correct confidence level, sample mean, population standard deviation, and sample size. Then view the confidence interval indicated on the x-axis to find your answer. Please note, you'll need to use the sliders above the graph to change the x-axis markers.
