Question

The following are the expected values and standard deviations for the number of times per month that the families prepare chicken for dinner. Kubelka family: u = 11.1 times a month, o = 2.4 times Proa family: u = 8.5 times a month, o = 1.75 times Ye family: u = 9.7 times a month, o = 4.2 times Devore family: u = 4.2 times a month, o = 1.1 times
a. How many total times per month do the families prepare chicken? Standard deviation?
b. How many more times a month would you expect the Kubelka family to prepare chicken than the Devore family? Standard deviation?
c. If the Ye family typically spends $15 on ingredients each time they prepare chicken, how much money would you expect them to spend each month on their chicken dinners? Standard deviation?
d. The Proa family has decided to try to replace one meal a week that they typically ate pork with a chicken dish. How many times per month would we expect the Proa family to prepare chicken now? Standard deviation?
e. The Proa family typically spends $10 on ingredients each time they prepare chicken while the Devore family typically spends $18 on ingredients each time they prepare chicken. Which family would you expect to spend the most each month? How much more? Standard deviation?
