A manager records the repair cost for 4 randomly selected TVs. A sample mean of $76.83 and standard deviation of $11.44 are subsequently computed. Determine the 99% 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.
