Population of scores with a mean

Assume we have a population of scores with a mean (?) of 975 and a standard deviation (?) of 15. Suppose that the distribution is normal. Provide answers to the following questions:

a. What percentage of population will lie between 960 and 990?

b. What percentage of population will lie below 975?

c. What percentage of population will lie below 990?

d. What two values of X (the counts) would encompass the middle 50 percent of scores?
