2Required informationThe article "Multi-objective Scheduling Problems: Determination of Pruned Pareto Sets" (H. Taboada and D. Coit, IIETransactions, 2008:552-564), presents examples in a discussion of optimization methods for industrial scheduling andproduction planning. In one example, seven different jobs were performed on each of five machines. The means andstandard deviations of the processing times for each machine are presented in the following table.MachineMeanSDSample SizeA25.4310.677B23.7113.927kC44.5715.907tDE23.1412.75758.0019.117i<ncesConstruct an ANOVA table.

A sports psychologist studied the effect of a motivational program on number of injuries in one year among players of three different sports (baseball, football, and basketball). Players were randomly assigned to one of two conditions: either participate in a motivational program or none (control). Data was collected on the number of injuries sustained by each athlete that season. Question: As taught in 510/515, what is the most appropriate graph if all main effects and interactions in this scenario were significant?
12. Western Pygmy-Possum. The foraging behavior of the west- ern pygmy-possum was investigated in the article “Strategies of a Small Nectarivorous Marsupial, the Western Pygmy-Possum, in Re- sponse to Seasonal Variation in Food Availability" (Journal of Mam- malogy, Vol. 96, No. 6, pp. 1525–1535) by D. Morrant and S. Petit. The weights of adult male pygmy-possums in Australia are normally distributed with a mean of 8.5 g and a standard deviation of 0.3 g. a. Sketch the normal curve for the pygmy-possum weights. b. Find the sampling distribution of the sample mean for samples of size 4. Draw a graph of the normal curve associated with ĩ. c. Repeat part (b) for samples of size 9.
Learning math Developers of a new math curriculumcalled “Accelerated Math” compared performances ofstudents taught by their system with control groups ofstudents in the same schools who were taught using traditional instructional methods and materials. Statis-tics about pretest and posttest scores are shown in the table. (J. Ysseldyke and S. Tardrew, Differentiating MathInstruction, Renaissance Learning, 2002)a) Did the groups differ in average math score at thestart of this study? b) Did the group taught using the Accelerated Math pro-gram show a significant improvement in test scores? c) Did the control group show a significant improve-ment in test scores? d) Were gains significantly higher for the AcceleratedMath group than for the control group?

Develop the estimated regression equation that relates annual maintenance expense (in hundreds of dollars) to weekly usage hours (to 3 decimals). Expense = + Weekly Usage b. Test the significance of the relationship in part (a) at a 0.05 level of significance. Compute the value of the F test statistic (to 2 decimals). The p value is less than 0.01 What is your conclusion? S Conclude that there is a significant relationship between expense and weekly usage c. Jensen expects the new machine to be used 30 hours…

A cellphone provider has the business objective of wanting to determine the proportion of subscribers who would upgrade to a new cellphone with improved features if it were made available at a substantially reduced cost. Data are collected from a random sample of 500 subscribers. The results indicate that 123 of the subscribers would upgrade to a new cellphone at a reduced cost. Reducing the price will be profitable if at least 20% of the subscribers would upgrade. Complete parts (a) and (b) below. a. At the 0.05 level of significance, is there evidence that more than 20% of the customers would upgrade to a new cellphone at a reduced cost? Determine the null hypothesis, Ho, and the alternative hypothesis, H₁ . ▶
