Working with proportion of population given mean, standard deviation and a subject's score.

mean=76, standard deviation=12; Subject Q had a score of 70. a. What proportion of the population scored below Q? b. If you changed the mean to 100 and the standard deviation to 10, what would Q's score be?

Consider the three values of mean and the three values of standard deviation
