Problem 60

Milk Although most of us buy milk by the quart or gallon, farmers measure daily production in pounds. Ayrshire cows average 47 pounds of milk a day, with a standard deviation of 6 pounds. For Jersey cows, the mean daily production is 43 pounds, with a standard deviation of 5 pounds. Assume that Normal models describe milk production for these breeds. a) We select an Ayrshire at random. Whats the probability that she averages more than 50 pounds of milk a day? b) Whats the probability that a randomly selected Ayrshire gives more milk than a randomly selected Jersey? c) A farmer has 20 Jerseys. Whats the probability that the average production for this small herd exceeds 45 pounds of milk a day? d) A neighboring farmer has 10 Ayrshires. Whats the probability that his herd average is at least 5 pounds higher than the average for part cs Jersey herd?
