a. If only the top 1% of the test takers would be considered for scholarships at Prestige College, what is the minimum score for the scholarship group?
--------------------
Find the z-value that separates the top 1% of a population from
the lower 99%. That value is invNorm(0.99) = 2.3263
-------------------
Find the raw score value associated with that z-value:
x = u + z*sigma
x = 21.3 + 2.3263*6 = 35.28
