for your work package was five days, yes.

9-Your manufacturing plant has 20 identical machines, each of which which perform a vacuum seal test on hundreds of glass ampuoles per day. Each machine inspects the product from a sealing machine immediately behind it. The testing machines are checked and serviced by the manufacturer on a weekly basis, and are guaranteed to be running according to specifications. Each line produces an average of only 3 or 4 defective ampuoles per day. These are discarded as scrap. You are going to set up a QC program to monitor the performance of the sealing machines and keep them working well. What kind of Quality Control Chart would you want to employ in this program?
a.X-bar cha
b.R chart
c.p chart
d.c chart
8-You are a buyer bidding sight unseen on a lot of 10,000 uncut diamonds. You are able to take a random sample of 100 stones from the lot. You determine that the mean weight of the sample is 1.52 ct with a standard deviation of 0.11 ct. Before making a bid, you need to estimate the percentage of the stones which will yield a finished or cut diamond of less than 1.00 ct. You know that on average, the cutting and finishing process yields a stone with 2/3 the weight of the uncut raw material. Based on this information, what would you estimate the number of "rejects" (stones yielding a finished diamond of less than 1.00 ct) to be?
7-An American style roulette wheel has individual compartments for the numbers 1 to 36 inclusive, plus 0 and 00. If a bettor bets on a single number and hits, he gets a payoff of 35:1, assuming that the wheel has not been tampered with. That is to say, on a $1 bet, if the number comes up, the bettor receives $35. If the number does not come up, he loses his $1 bet. A bettor steps up to a regulation wheel at Atlantic City with $1,000 worth of chips. He begins to place single-number bets of $10 each, one at a time. After 100 bets have been placed, what is the expected value of the chips that the bettor has?
6-The USDA size standards for eggs are based on weight and are as follows:
SMALL: greater than 43 grams, less than 50 grams
MEDIUM: greater than 50 grams, less than 57 grams
LARGE: greater than 57 grams, less than 64 grams
EXTRA LARGE: greater than 64 grams, less than 71 grams
JUMBO: greater than 71 grams
The output of a particular egg farm has a mean weight of 62 grams with a standard deviation of 8 grams. What is the size category in which most of the eggs from this farm fall?
a-SMALL or smaller.
b-MEDIUM
c-LARGE
d-EXTRA LARGE and LARGER
5- You are a Delaware State Trooper on a roadblock. Since it is New Years' Eve, you know from prior experience that approximately 5% of the drivers on the road have a blood alcohol content (BAC) over the legal limit of 0.08%. Your portable brethalyzer gives a PASS/FAIL reading. From prior experience and the manufacturer's data, you know that the breathalyzer has a "hit rate" of 90% and a "false positive rate" of 20%. This means that if the breathalyzer says "FAIL," there is a 90% chance of it being correct if the subject is legally DUI and a 20% chaance of a FAIL reading even if the subject is not legally intoxicated. You stop a driver at random and test him. He blows a "PASS," so you let him go. What is probability that the driver was legally DUI?
