Question

Transcribed Image Text:A random sample of 10 fields of corn has a mean yield of 37.1 bushels per acre and standard deviation of
5.91 bushels per acre. Determine the 98 % 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.
