Answer to the Q63 is as follows. Please don't hesitate to give a "thumbs up" in case you're satisfied with the answer.
63.
the params of normal distribution are given by low:
Mean = 79 inches
Sigma = 3.89 inches
a. 77 inches = ?
Z = (X-Mu)/Sigma = (77-79)/3.89 = -0.514
It means that somebody with height 77 inches will lie in the a 30.36% percentiler i.e. will be in the bottom 30.36% of people
b. 85 inches = ?
Z = (X-Mu)/Sigma = (85-79)/3.89 = 1.5424
It means that somebody with height 85 inches will lie in the a 93.85% percentiler i.e. will have 93.85% of peeople will have lesser score than his.
c. No, a score of Z = 3.5 means he lies in top .02% of heights, which is highly impossible and hence I wouldn't beeive him.
