Q1b,
The average height of a group of student is 68 inches with a standard deviation of 3 inches. The average shoe size is in this same group is 11 with a standard deviation of 2. If the covariance between them is 3.732, what is the variance of Height - ShoeSize? 3 different type of grains are sold by a farmer. Let X1, X2 and X3 be the weight of each grain with means 100, 200, and 300 pounds...

Q1B:
Anita's, a fast-food chain specializing in hot dogs and garlic fries, keeps track of the proportion of its customers who decide to eat in the restaurant (as opposed to ordering the food "to go"), construction of in-store play areas, the attendance of its mascot Sammy at the franchise locations, and so on. Anita's reports that 45% of its customers order their food to go. If this proportion is correct, what is the probability that, in a so it...
