The average amount of corn yield is normally distributed with a mean of 168.7 bushels of corn per acre, with a standard deviation of 27 bushels of corn. In an agricultural study, 81 randomly selected acres were harvested. What is the probability that the mean corn yield of these 81 acres is less than 165 bushels of corn? Round your answer to 3 decimal places. Question 4 (1.5 points) A Please upload an image of your scratch work for the prior problem. This should include a sketch of the sampling distribution (the bell curve - as demonstrated in the lesson).
