A farmer wants to compare the mean number of watermelons he harvests across his 25 fields (n=25) annually to the national average. The mean number the farmer harvests is x=806 and the national mean is u=800. The farmer determines the sample standard deviation is s=14.27. Perform all 4 steps of a one sample t-test to determine if the farmer's annual harvest is statistically different from the national harvest (a=0.05)
