At a bank, average credit score of a 35 yr old is normally distributed with a mean of 600 and std dev of 100.

a. score for top 5%

b. 75% of applicants will have at least what score?

c. Between what two credit scores will 80% of the applicants fall if the applicants are symmetrically distributed?

Please help thanks!

doesn't this problem involve finding the z score? but 5-600/100 = a number outside the chart
