The score for freshmen on an aptitude test at WSU Vancouver has mean of 560, with a standard deviation of 38. Assume the means to be measured to any degree of accuracy; hence grades can be any nonnegative real number. Two random samples are selected, one with 38 scores and one with 44 scores. What is the probability that two random samples will differ in their mean scores by less than 20 points? P(|X₁ X₂ <20) =[ 2
