To estimate his corn yield in bushels per acre a farmer randomly selected 50 ears of corn from his corn field. The summary statistics for the number of kernels of corn on these ears were =760 kernels and =40 kernels. a) Construct and interpret a 95% confidence interval for the mean number of kernels of corn for all ears of corn growing in his field. Assume that the conditions for inference are satisfied. b) Assume that 1 acre of corn produces 26,000 ears and that it takes 90,000 kernels of corn for 1 bushel of corn. Use your answer from part (a) to estimate the mean number of bushels of corn per acre with 95% confidence.
