Zоuаr Cоmputer Cоrporаtion currently mаnufactures the disk drives that it uses in its computers. The costs to produce 5,000 of these disk drives last year were as follows: Cost per drive Direct materials $ 12 Direct labor 2 Variable manufacturing overhead 5 Fixed manufacturing overhead 7 Total $ 26 Kidal Electronics has offered to provide Zouar with all of its disk drive needs for $27 per drive. If Zouar accepts this offer, Zouar will be able to use the freed up space to generate an additional $40,000 of income each year to produce more of its computer keyboards. Only $3 per drive of the fixed manufacturing overhead cost above could be avoided. Direct labor is an avoidable cost in this decision. Based on this information, would Zouar be financially better off making the drives or buying the drives and by how much?

Intrо. tо Stаts – Test Shоw working Consider the following dаtа: Condition Present Condition Absent Test Result + 150 10 Test Result - 25 70 One person is randomly selected from the group (a) Find Prob( Test Result - ) (b) Find Prob( Test Result + and Condition Absent ) For the data in question 1, find: (a) Prob( Condition Present | Test Result - ) (b) Prob( Test Result + | Condition Absent ) If P(A)=0.65, P(B)=0.1 and P(A or B)=0.3, find P(A and B). Are the events in question 3 mutually exclusive ? Explain. Laura has 7 Stats textbooks that she is going to place on a shelf. How many different arrangements of the books are possible if the order of the books on the shelf matters to Laura. A university advertises to fill 2 positions for Statistics teachers. 23 people apply. In how many ways can the positions be filled ? (a) Calculate 7P3 (b) Calculate 14C0 X 0 1 2 3 P(X) 0.7 0.05 ? 0.1 What does P(2) equal for this to be a probability distribution? What is the expected value of the probability distribution in question 8. a) For a binomial experiment, how many outcomes are possible for each trial ? b) In a binomial experiment, is it possible for the probability of success to change from one trial to the next ? Consider a binomial experiment with n=10 trials where the probability of success on a single trial is p=0.7. Find Prob(r=4). (a) What is the expected value of the binomial distribution in question 11 ? (b) What is the standard deviation of the binomial distribution in question 11 ? An unfair coin has prob(heads)=0.4. The coin is tossed. What is the prob. that the first tail occurs on the 7th toss ? ( Hint. Note that the word first is underlined ). A gale force wind occurs on average once every 60 hours on a mountain road. For an interval of 300 hours, what is the prob. that 3 gale force winds are experienced ? ( Hint, use a Poisson distribution. ) Cleo is a 65% basketball free throw shooter. She is interested in how many attempts it takes to make 4 baskets. What is the probability that it takes 12 attempts ? ( Hint. Note that the number of attempts is the variable in this question .) What is the mean and standard deviation of the Standard Normal distribution ? 17. What does a z-score represent ? 18. Consider a normal distribution with mean=20 and standard deviation=4 (a) Find a z value corresponding to an x value of 14 (b) Find the data value corresponding to a z value of 1.5 19. Find the area under the standard normal curve (a) To the right of z=1.52 (b) Between z=1.40 and z=2.03 20. If x has a normal distribution with mean=40 and standard deviation=15, find Prob ( 30
