Calculate the test statisticsThe amount of a certain trace element in blood is known to vary with a variance of 198.81 ppm (parts per million) for male blood donors and 90.25 ppm for female donors. Random samples of 75 male and 50 female donors yield concentration means of 28 and 33 ppm, respectively.Subj: Statistics and probability
