A nonprofit analyst considered two independent variables as a predictor for the dependent variable Commitment, the percent of total expenses that are allocated to charitable services. The independent variables are Revenue, total revenue in billions of dollars, andEfficiency, the percent of private donations remaining after fundraising expenses. The regression analysis resulted in this ANOVA table. Determine whether there is a significant relationship between commitment and the two independent variables at the 0.01 level of significance.

ABC Company is exploring different prediction models that can be used to forecast indirect labor costs. One independent variable under consideration is machine hours. Following are matching observations on indirect labor costs and machine hours for the past six months: Machine hours Indirect labor costs P20,000 P24,000 P17,000 P22,000 P13,000 P14,000 Month 1 300 400 240 4 370 5 200 6 225 Using linear regression analysis, the estimated variable indirect labor cost per machine hour is closest to: P35.62 P15.44 P52.71 P58.31

Grade Prediction. The Statistics Department at a large university would like to predict the final grades of students in its introductory statistics course. a. If the final grade is measured as a percentage from 0% to 100%, suggest five predictor variables that might be useful in predicting final grade. b. Write the multiple linear regression model for the conditional mean of the response variable, final grade.

Scientific mass appraisal is a technique in which linear regression methods applied to the problem of property valuation. The objective in the Scientific Mass Appraisal is to predict the sale price of a home from selected characteristics of the building and taxes paid on the buildingTwenty four observations were obtained. The list of variables is also given.Answer the following questions, in each case justifying your answer by appropriate analyses.(a) In a fitted regression model that relates the sale price to taxes and building characteristics, would you include all the variables?(b) A veteran real estate agent has suggested that local taxes, number of rooms and age of the house would adequately describe the sale price . Do you agree ?(c) A real estate expert who who was brought into the project reasoned as follows:“ The selling price of a home is determined by its desirability and this is certainly a function of the physical characteristic of the building. This overall assessment is…
