A standard package of Oreos is supposed to contain 510 grams of chocolatey goodness. But there’s variation in just about anything, including production and packaging, so some packages will contain more and some will contain less. In fact, this is exactly the sort of quantity that tends to be
Let’s say that the mean is 518 grams and the standard deviation is 4 grams.
a. Fill in all of the blanks on the empirical rule diagram below with weights in grams. Use the formulas below the blanks for reference.
b. What percent of all Oreo packages would contain between 514 and 522 grams?

- Jean Clark is the manager of the Midtown Saveway Grocery Store. She now needs to replenish her supply of strawberries. Her regular supplier can provide as many cases as she wants. However, because these strawberries already are very ripe, she will need to sell them tomorrow and then discard any that remain unsold. Jean estimates that she will be able to sell 10, 11, 12, or 13 cases tomorrow. She can purchase the strawberries for $3 per case and sell them for $8 per case. Jean now needs to decide how many cases to purchase. Jean has checked the store’s records on daily sales of strawberries. On this basis, she estimates that the prior probabilities are 0.2, 0.4, 0.3, and 0.1 for being able to sell 10, 11, 12, and 13 cases of strawberries tomorrow. 4. If Jean is dubious about the accuracy of these prior probabilities and so chooses to ignore them and use the equally likely criterion, how many cases of strawberries should she purchase?

If the part is too long, it must be trimmed to the correct length. Suppose 5% of all parts are too long and 1% of all parts are too short. Parts of the correct length (either originally or trimmed) can be sold for $5 each. However, if the part is too short, it cannot be used at all and is discarded. The cost of manufacturing each part is $2 and the cost to trim a part to length is $1. The expected profit per part is: (A) $1.00 (B) $2.05 (C) $2.90 (D) $3.00 (E) $4.95arrow_forward
- Opinions are split about a coffee company's pumpkin-flavored coffee (PFC). Yet every year over the last five years the consumption of pumpkin-flavored goods has increased. If we look at the numbers, it also becomes clear why a leading coffee company keeps offering the PFC earlier and earlier every year. According to a magazine, the amount spent by PFC buyers at the coffee company is about 17% higher than non-PFC buyers. The accompanying table shows a random sample of eight consumers, the amount they spend per week, y, and the number of PFCs purchased, x, per week.
