The following distribution is for two populations (A and B) that have normal distributions for cholesterol. with known standard deviations and based on sample size 20. The shaded area in the given distribution is 0.475. If a sample (n=20) was taken from each population what is the probability that sample A is at least 9 units higher than that of sample B.
