- . A student scored 70 on a physics exam where theclass mean is 80 and a SD of 9. He scored 60 on aStatistics exam with a mean of 62 and a SD of 4. Inwhich class his relative position is higher.The systolic blood pressure (given in millimeters) of males has an approximately normal distribution with mean µ = 125 and standard deviation σ = 14. Systolic blood pressure for males follows a normal distribution. Calculate the z-scores for the male systolic blood pressures 100 and 150 millimeters. Is there a way to solve in excel?Solve for the z-score each item and show the illustration (drawing of) of normal curve please clarify the letter
