The composite scores of individual students on the ACT college entrance examination in 2009 followed a normal distribution with mean 21.1 and standard deviation 5.1. What is the probability that a single student randomly chosen from all those taking the test scores 23 or higher? P(X > 0.3548) = P(z > 0.3725) = 0.3725 What is the probability that a simple random sample of 50 students chosen from all those taking the test has an average score of 23 or higher? p(X >) = p(z >) = Why is it more likely that a single student would score this high instead of the sample of students?

Acoffee shop orders at most $3,500 worth of coffee and tea. the shop needs to make a profit of at least $1,900 on the order. the possible combinations of coffee and tea for this order are given by this system of inequalities, where c = pounds of coffee and t = pounds of tea: 6c + 13t ≤ 3,500 3.50c + 4t ≥ 1,900 which graph's shaded region represents the possible combinations of coffee and tea for this order?
