A farmer was interested in determining how many grasshoppers were in their field. They know that the distribution of grasshoppers may not be normally distributed in their field due to growing conditions. As they drives their tractor down each row they counts how many grasshoppers they see flying away, X. After several rows they figure the mean number of flights to be u = 57 with a standard deviation of o = 12. What is the probability of the farmer will count an average (mean) of 54 or fewer flights in the next n = 40 rows in which they drive their tractor? i.e. find P( Xs 54). In calculating the z-score, round
