The number of loaves of bread sold per day by an organic bakeryover the past five years can be treated as a random variable thatis normally distributed. This distribution has a mean of 77.5 and astandard deviation of 14.4 loaves. Suppose a random sample of 36days has been selected. Determine the probability that the averagenumber of loaves sold in the sample of days exceeds 80 loaves.First find the standard error of the mean.
Now calculate the Z (Standard) Score. Round your answer to twodecimal places
Now find the probability that the average number of loaves soldin the sample of days exceeds (is greater than) 80 loaves.
