Question: Calculate: a) Z-score for a random variable X = 60 is normally distributed with mu=50, standard deviation=8. b) P(0.21 Z 1.69) c) Find the Z-score

Calculate:

a) Z-score for a random variable X = 60 is normally distributed with mu=50, standard deviation=8.

b) P(0.21 Z 1.69)

c) Find the Z-score such that the area to the right of the Z-score is 0.483.

d) Find the Z-score that separate the middle 88% of the data from the area in

the tails.
