A student records the repair cost for 6 randomly selected stereos. A sample mean of $65.62 and standard deviation of $24.23 are subsequently computed. Determine the 90% confidence interval for the mean repair cost for the stereos. 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.
