A grocer checks 200 apples and finds that 8 are spoiled. On average, how many apples are spoiled in a bag of ten? (Hint: spoilage will follow a Poisson distribution, let n=10 and π is the empirical probability.) Multiple choice question. 2 0.2 0.4 0.04

Step 1
Number of spoiled apples = 8 Total apples checked = 200 Empirical probability, π = 8 / 200 = 0.04 Show more…

Suppose that Stephen is the quality control supervisor for a food distribution company. A shipment containing many thousands of apples has just arrived. Unknown to Stephen, 14% of the apples are damaged due to bruising, worms, or other defects. If Stephen samples 10 apples from the shipment, use the binomial distribution to estimate the probability that his sample will contain at least one damaged apple. Give your answer as a decimal precise to at least four decimal places.

Your undergraduate Public Health club is planning a campus event to distribute healthy snacks during this weekend's feather bowling championship. Two local vendors are bidding to supply you with fruit for the event, and you want to be sure you pick the market with the freshest fruit, so you've sent some secret shoppers to check out their supplies. The Wayne Market team checked out 600 apples and 400 oranges, and found that 20 of each were rotten. The Cass Grocery team only got through 200 apples and 200 oranges before the shopkeeper kicked them out, but not before noting that 10 apples and 5 oranges had spoiled. Calculate the fruit-specific spoilage rate at each store. You know that people prefer apples over oranges, so you'll buy 2000 apples and 1000 oranges, and to save time, you'll only go to one store. Which store would you choose to get the fewest rotten fruit? How many rotten fruit do you expect at that store? Show your calculations to justify your answers. If you could buy apples and oranges separately, which store would you go to for each?
