A student records the repair cost for 17 randomly selected washers. A sample mean of $82.95 and standard deviation of $14.89 are subsequently computed. Determine the 80% confidence interval for the mean repair cost for the washers. Assume the population is approximately normal. Step 1 of 2: Find the critical value that should be used in constructing the confidence interval. Round your answer to three decimal places. Step 2 of 2: Construct the 80% confidence interval. Round your answer to two decimal places. Lower Endpoint: Upper Endpoint:
