X-74 X1 = 7. 6. The quality grade-point average of 300 college freshmen follow approximately a normal distribution with a mean of 2.1 and a standard deviation of 0.8. How many of these freshmen would you expect to have a score between 2.5 and 3.5 inclusive of the point averages are computed to the nearest tenth? Z2 = P(2.5 < X < 3.5) = P < Z <_ = P(Z__- P(Z__ Approximately of the 300 freshmen, should have a score between 2.5 and 3.5. Property of and for the exclusive use of SLU.
