The article "Case Study Based Instruction of DOE and SPC" (J. Brady and T. Allen, The American Statistician, 2002:312-315) presents the result of a 24-1 factorial experiment to investigate the effects of four factors on the yield of a process that manufactures printed circuit boards. The factors were A: transistor power output (upper or lower specification limit), B: transistor mounting approach (screwed or soldered), C: transistor heat sink type (cUIrent or alternative configuration), and D: screw position on the frequency adjustor (one- half or two turms). The results are presented in the following table. The yield is a percent of a theoretical maximum. в Yield 79.8 -1 -1 -1 -1 69.0 -1 72.3 71.2 91.3 -1 -1 95.4 -1 92.7 91.5 a. Estimate the main effects of each of the four factors. b. Assuming all interactions to be negligible, pool the sums of squares for interaction to use in place of an erIor sum of squares. Which of the four factors, if any, can you conclude to affect the yield?…
A manufacturing company employs two inspecting devices to sample a fraction of their output for quality control purposes. The first inspection monitor is able to accurately detect 99.3% of the defective items it receives, whereas the second is able to do so in 99.7% of the cases. Assume that four defective items are produced and sent out for inspection. Let X and Y denote the number of items that will be identified as defective by inspecting devices 1 and 2, respectively. Determine the following. 1) fxy(x,y) 2) fx (x)3) fY|2 4) E(x)Show all work
A study was conducted to determine whether big-city and small-town dwellers differed in their helpfulness to strangers. In this study, the investigators rang the doorbells of strangers living in a large City or small towns in the vicinity. They explained they had misplaced the address of a friend living in the neighbourhood and asked to use the phone. The following data show the number of individuals who admitted or did not admit the strangers (the investigators) into their homes: Helpfulness to strangers Admitted strangers into their home Didnot admit strangers into their home Big city dwellers 60 90 Small town dwellers 70 30 State the dependent and independent variable Is this a directional or non directional
A study of fox rabies in southern Germany gave the following information about different regions and the occurrence of rabies in each region. A random sample of n1 = 16 locations in region 1 gave the following information about the number of cases of fox rabies near that location. x1: Region I Data 3 7 8 7 5 8 8 1 3 3 3 2 5 1 4 6 A second random sample of n2 = 15 locations in region II gave the following information about the number of cases of fox rabies near that location. x2: Region II Data 4 2 4 1 3 8 5 4 4 4 2 2 5 6 9 Note: If a two-sample t-test is appropriate, for degrees of freedom d.f. not in the Student's t table, use the closest d.f. that is smaller. In some situations, this choice of d.f. may increase the P-value by a small amount and therefore produce a slightly more "conservative" answer.Use a calculator with sample mean and sample standard deviation keys to find x1 and s1 in region I, and x2 and s2 in region II.

4. A cigarette company is interested in the effect of several conditions of smoking on steadiness. They manufacture two brands: Old Zincs and Counts. Furthermore, they make each brand with and without a filter. In the smoking experiment, the higher the score, the greater was steadiness. Assume that the results came out as follows (10 participants per cell). What conclusions did the experimenter reach? With Filter Without Filter Old Zincs 7 2 7 2 8 3 8 3 9…
A manufacturing company employs two inspecting devices to sample a fraction of their output for quality control purposes. The first inspection monitor is able to accurately detect 99.5% of the defective items it receives, whereas the second is able to do so in 99.7% of the cases. Assume that four defective items are produced and sent out for inspection. Let X and Y denote the number of items that will be identified as defective by inspecting devices 1 and 2, respectively. Assume the devices are independent. Determine (a) the range of the joint probability distribution of X and Y. (b) fxy(*, y). (c) fx(x). (d) E(X). e) fy|x=3(y).
The Higher Education Research Institute at UCLA collected data from incoming first-time, full-time freshmen from 290 four-year colleges and universities in the U.S. In 2019, 56% of those surveyed strongly agree that addressing global climate change should be a federal priority. Suppose that you randomly pick 10 first-time, full-time freshmen. You are interested in the number of these 10 that strongly agree that addressing global climate change should be a federal priority. a. Identify the parameter n for the binomial experiment. b. Identify the parameter p for the binomial experiment. c. Find the probability that fewer than 6 of the 10 strongly agree that addressing global climate change should be a federal priority. Round your answer to 4 decimal places.
