Postby Guest » Fri Oct 14, 2016 8:04 pm

Hello luvs, I'm trying to figure out these z score problems and would really appreciate it if someone could help me out! Thanks so much! :oops:

a. What percentage of cases are below those with a Z-score of -1.75?
b. What percentage of cases are between a Z score of 1.25 and 2.25?
c. Is a person whose Z-score is -1.75 an outlier?
d. Is a person whose Z-score is 3.50 an outlier?
e. A persons SD is 0.50. What is his Z-score?
f. What percentage of cases are above those with a Z-score of -0.50?
g. What percentage of cases are above a Z-score of 0.50?
