A supervisor records the repair cost for 17 randomly selected TVs. A sample mean of $57.20 and standard deviation of $26.41 are subsequently computed. Determine the 80% confidence interval for the mean repair cost for the TVS. 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.
