Determine the p-value that will result when testing the following hypotheses for experiments involving two independent samples:
a. Ho: Average(A) = Average(B); Ha: Average(A) > Average(B); with nA = 18, nB = 15, and U = 95
b. Ho: Average(I) = Average(II); Ha: Average(I) ≠ Average(II); with nA = 8,nB = 10, and U = 13
c. Ho:The average height is the same for both groups; Ha: Group I average height is shorter than group II; with nI = 50 nII = 45 and z = - 2.37
