Chapter 7 #42 The accounting department at Weston Materials‚ Inc.‚ a national manufacturer of unattached garages‚ reports that it takes two construction workers a mean of 32 hours and a standard deviation of 2 hours to erect the Red Barn model. Assume the assembly times follow the normal distribution. a. Determine the z values for 29 and 34 hours. What percent of the garages take between 32 hours and 34 hours to erect? z(29) = (29-32)/2 = -3/2 z(34) = (34-32)/2 = 1 z(32) = 0 P(32 < x <

8.1 BINOMIAL SETTING? In each situation below‚ is it reasonable to use a binomial distribution for the random variable X? Give reasons for your answer in each case. (a) An auto manufacturer chooses one car from each hour’s production for a detailed quality inspection. One variable recorded is the count X of finish defects (dimples‚ ripples‚ etc.) in the car’s paint. No: There is no fixed n (i.e.‚ there is no definite upper limit on the number of defects). (b) The pool of potential jurors for

No. 5 - Standards of Legitimacy: In order to have a negotiated agreement that seems fair to all parties‚ the parties should utilize “standards of legitimacy.” These standards should “preferably be objective and outside of the ability of any one party to control.”6 The current procedures in place for determining fault in an officer’s behavior and assigning punishment are technically part of an official standard‚ but they are within the police department’s ability to control and thus cannot count as

#1 True or false: Even if the sample size is more than 1000‚ we cannot always use the normal approximation to binomial. Solution: If a sample is n>30‚ we can say that sample size is sufficiently large to assume normal approximation to binomial curve. Hence the statement is false. #2 A salesperson goes door-to-door in a residential area to demonstrate the use of a new Household appliance to potential customers.

Standards 2‚ 4‚ and 5 were met in the previously submitted report‚ therefore the associated documents may include identification of these standards but the following narrative will not be included in this revised report. This revised report will only address standards 1 and 3‚ as they are the standards that have been met with conditions. The National Recognition Report states that the following conditions must be met in order to obtain full national recognition: • Candidate pass rate is inconsistent
