. Christy operates a business called Dinner to Go! that provides home-cooked meals for people that don't have time to cook for themselves. Each meal consists of a main dish and two side dishes. Bob operates a similar business across town called Let Me Feed You. They decide to combine their operations. Both of them will continue working independently from their own locations, but Christy will provide the side dishes and Bob will provide the main dish. The mean amount of time it takes Christy to make the side dishes for one day is 4.2 hours with a standard deviation of 0.8 hours. The mean amount of time it takes Bob to make the main dishes for one day is 5.1 hours with a standard deviation of 1.1 hours. The price customers are charged will be based in part on the total time spent preparing the meals. Find the mean and standard deviation for the total amount of time necessary to make the side dishes and main dish for one day. (A) mean = 9.30 hours, standard deviation = 1.90 hours (B) mean = 9.30 hours, standard deviation = 1.85 hours (C) mean = 9.30 hours, standard deviation = 1.36 hours (D) mean 4.65 hours, standard deviation = 1.90 hours = (E) mean 4.65 hours, standard deviation = 1.36 hours

will provide the side dishes and Bob will provide the main dish. The mean amount of time it takes
Christy to make the side dishes for one day is 4.2 hours with a standard deviation of 0.8 hours. The
mean amount of time it takes Bob to make the main dishes for one day is 5.1 hours with a standard
deviation of 1.1 hours. The price customers are charged will be based in part on the total time spent
preparing the meals. Find the mean and standard deviation for the total amount of time necessary to
make the side dishes and main dish for one day.
