The retail price of a mediumsized box of a well-known brand of cornflakes ranges from 13 to 7.5. Assume these prices are uniformly distributed. What are the average price and standard deviation of prices in this distribution? If a price is randomly selected from this list. what is the probability that it will be between 27 and 69 P(27 gal/.69) =| Use the data given to test the following hypotheses Ha: p = 1200 H\": p. a 1200 :E = 1220; cr = 110.1: 2 102 and a = [1.05.
