A random sample of 66 fields of corn has a mean yield of 21.621.6 bushels per acre and standard deviation of 6.026.02 bushels per acre. Determine the 99%99% confidence interval for the true mean yield. 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.
