T test uses means and standard deviations of two samples to make a comparison. Sample sd 9 960316 95 confidence interval for mean difference 5 388429 to 14 711571 df 19. Where m is the sample mean.
Sample size n 20.
μ 310 population mean is equal to 310 pounds h1. This is the mean of the sampling distribution of the sum of ranks for a sample of nitems. Standard deviation of second set of values. S is the sample standard deviation with n 1 degrees of freedom.
