Suppose the mean of a math exam score is 70 with a standard
deviation of 20. If each score is increased by 2 and then each result is
multiplied by 1.05, then new mean and standard deviation are
a. µ = 75.6 and o = 21.0
O b. µ = 75.6 and o = 22.6
O c.p = 75.6 and o = 20.0
O d.u = 72.0 and o = 22.0
O e.p = 76.5 and o = 20.1
