A student records the repair cost for 17 randomly selected washers. A sample mean of $82.95 and standard deviation of $14.89 are subsequentlycomputed. 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.
