n a random sample of 39 residents of the state of Florida, the mean waste recycled per person per day was 2.1 pounds with a standard deviation of 0.87 pounds. Determine the 95% confidence interval for the mean waste recycled per person per day for the population of Florida. Assume the population is normally distributed. Step 1 of 2 : Find the critical value that should be used in constructing the confidence interval. Round your answer to three decimal places.
