Sat scores. sat scores of students at an ivy league college are distributed with a standard deviation of 250 points. two statistics students, raina and luke, want to estimate the average sat score of students at this college as part of a class project. they want their margin of error to be no more than 25 points. (a) raina wants to use a 90% confidence interval. how large a sample should she collect? (b) luke wants to use a 99% confidence interval. without calculating the actual sample size, determine whether his sample should be larger or smaller than raina's, and explain your reasoning.
