18. Amertron produces electrical wiring in 100-foot rolls. The quality inspection process involves selecting rolls of wire at random and counting the number of de- fects on each roll. The last 20 rolls examined revealed the following numbers of defects: Roll Number of Defects Roll Number of Defects 1 4 11 2 2 12 5 3 13 5 4 4 14 7 1 15 16 4 8 7 17 8 18 19 4 3 3 10 20 4 a. If the number of defects per 100-foot roll of wire follows a Poisson distribution, what is the estimate of c obtained from these observations? b. Using a normal approximation to the Poisson, what are the three-sigma control limits that you would use to monitor this process? c. Are all 20 observations within the control limits?

5. A market research company wishes to find out whether the population of students at a university prefers brand A or brand B of instant coffee. A random sample of students is selected, and each students is asked first to try brand A and then to try brand B , or vice versa (with the order determined at random). They then indicate which brand they prefer. This is an example of an experiment. b. а. an observational study a stratified sampling design. a randomized block design. a systematic sampling design. с. d. е.

10:27 Bb M QUESTION 2 Consider a one-item survey as follows: Using a scale of 1 – 5 in which 1 = Not as well as I hoped, 2 = Pretty well, 3 = Well, 4 = Very well, and 5 = Crushing it, please indicate how well you are doing so far in your MBA 503 course. 1[] 2[] What type of data does this survey generate? Choose all that apply. 3[] 4[] 5[ ] O Continuous O Ratio Time series O Exponential O Binomial O Interval O Biased O Intersection Union O Hypergeometric O Ordinal O None of the above QUESTION 3 If you have a data set of n items, the data are continuous variables, the data set is unimodal, and the data set is too skewed to use the normal distribution, which probability distribution should you use to calculate probabilities? O Discrete uniform distribution Binomial distribution O Poisson distribution Hypergeometric distribution O Geometric distribution O Uniform continuous distribution O Standard normal distribution O Exponential distribution O Triangular distribution O None of the above…

← 10:36 A-✔ MM.. +20 111 111 2010 Yesterday, 19:42 4a) The marketing and sales team for Dapple Corporation feel there is room in the market to introduce alternative designer branded merchandise into its range of laptops. This would mean outsourcing the manufacturing of accessories such as laptop covers. Due to the quick response times required to meet the demands of Dapple's customer orders, the designer brand manufacturer is proposing to set up a new manufacturing business unit close to Dapple Corporation to produce six new designs for designer laptop covers. Operations and purchasing are not convinced this arrangement will be cost effective and so wish to conduct a breakeven analysis of the situation to ensure the designer brand manufacturer's operation is profitable. The fixed costs for rent and labour are £5,000 per month. The Forecasted Sales Price, Variable Cost and Forecasted Monthly Sales Quantity for the six new products are given in Table 3 below.

A certain reagent is created to test for an infectious disease. The test has anaccuracy rate of p = 90%, and the accuracy does not depend on whether or not thepatient is actually infected. a. If four people are tested for the disease, what is the probability that at leastthree of them receive accurate test results? b. In an area where q = 5% of people are infected, a man’s test result ispositive. What is probability that it is a false positive (which means that he is notinfected but the test is positive due to inaccuracy)?   *please solve for a-b, type or neatly  write your answers on paper, NO EXCEL* thank you !
