The article "Case Study Based Instruction of DOE and SPC" (J. Brady and T. Allen, TheAmerican Statistician, 2002:312-315) presents the result of a 24-1 factorial experiment toinvestigate the effects of four factors on the yield of a process that manufactures printedcircuit boards. The factors were A: transistor power output (upper or lower specificationlimit), 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 ofa theoretical maximum.вYield79.8-1-1-1-169.0-172.371.291.3-1-195.4-192.791.5a.Estimate the main effects of each of the four factors.b.Assuming all interactions to be negligible, pool the sums of squares for interaction touse in place of an erIor sum of squares.Which of the four factors, if any, can you conclude to affect the yield? What is the P-value of the relevant test?C.

Note: in the scenario, the problem is based on Factorial experiment. Hence it is appropriate to use…

The article “Valuing Watershed Quality Improvements Using Conjoint Analysis” (S. Farber and B. Griner, Ecological Economics, 2000:63–76) presents the results of a mail survey designed to assess opinions on the value of improvement efforts in an acid-mine degraded watershed in Western Pennsylvania. Of the 510 respondents to the survey, 347 were male. Census data show that 48% of the target population is male. Can you conclude that the survey method employed in this study tends to oversample males? Explain.
30. Northwest Atlantic Cod. Researchers M. Kroll et al. studied the influence of paternity on rates of mortality and development in eggs and larvae of Northwest Atlantic cod in the article, “Paternal Ef- fects on Early Life History Traits in Northwest Atlantic Cod, Gadus morhua" (Journal of Applied Ichthyology, Vol. 29, Issue 3, pp. 623– 629). A sample of adult male Northwest Atlantic cod was collected in Nova Scotia, Canada.

The MAKSI FEB UI program is considering buying a copier machine among 5 (five) types, namely the FC1, FC2, FC3, FC4 and FC5 types, where each type has different efficiency in terms of the speed of the number of pages (sheets) copied in one minute. Six staff members conducted an experiment to run each type of copier. The following data shows the number of copied pages (sheets) that can be produced in one minute according to the type of copier, 1 trial, and according to the staff assigned to run each type of copier: FC1 FC2 FC3 FC4 FC5 Staff 1 60 50 63 60 64 Staff 2 56 55 65 58 60 Staff 3 54 56 65 56 58 Staff 4 56 57 67 65 60 Staff 5 54 56 65 60 60 Staff 6 55 52 58 60 55 Some of the results of the calculation of the sum of squares (sum-square) and the average squared (mean square) required for the ANOVA test are provided in the following table: Source of Variation SS Df MS Fstat FTable CopierMachine 333.33 ……… ……… ……… ……… Staff ……….. ……… ……… ……… ……… Error 129.47 ……… ……… Total 532.67 …………

A regional Internet service provider (ISP) is interested in whether a 15% discount on its price for its highest-speed service will notably impact customer retention. To answer this question, the ISP randomly chooses 75 of the 150 markets it serves to receive the 15% discount and keeps prices the same in the remaining 75 markets. After six months, the ISP observes the following: • For the markets receiving the discount, the average retention rate was 0.93 (i.e., 93%), with a standard deviation of 0.255. • For the markets not receiving the discount, the average retention rate was 0.88, with a standard deviation of 0.325. Using a 95% confidence interval, determine whether you can state with 95% confidence that the discount improved the six-month retention rate.
The article "Anodic Fenton Treatment of Treflan MTF" (D. Saltmiras and A. Lemley, Journal of Environmental Science and Health, 2001:261-274) describes a two-factor experiment designed to study the sorption of the herbicide trifluralin. The factors are the initial trifluralin concentration and the Fe?H202 delivery ratio. There were three replications for each treatment. The results presented in the following table are consistent with the means and standard deviations reported in the article.

The more costly and time-consuming it is to export and import, the more difficult it is for local companies to be competitive and to reach international markets. As part of an initial investigation exploring foreign market entry, 9 countries were selected from each of four global regions. The cost associated with importing a standardized cargo of goods by sea transport in these countries (in US$ per container) is stored in the accompanying data table. Complete parts (a) through (d).

An experiment was conducted to compare the effectiveness of four training programs, namely, A, B, C, and D in training assemblers of a piece of electronic equipment. Twenty employees were randomly selected and assigned to each program, that is, five employees per program. After completion of the training courses, each person was required to assemble four pieces of equipment, and the length of time (in secs) to complete the assembly was recorded. The summary of the data gathered is recorded in the table. At α=0.10, test for the hypothesis that the assembly times for people trained are the same for the four programs.

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.
