QuestionQuestion 1 2 / 2 pointsAccording to the following graphic, X and Y have:1) strong negative correlation2) virtually no correlation3) strong positive correlation4) moderate negative correlation5) weak negative correlationQuestion 2 2 / 2 pointsA cost accountant is developing a regression model to predict the total cost of producing a batch of printed circuit boards as a function of batch size (the number of boards produced in one lot or batch). The independent variable is:1) batch size2) unit variable cost3) fixed cost4) total cost5) total variable costQuestion 3 2 / 2 pointsA cost accountant is developing a regression model to predict the total cost of producing a batch of printed circuit boards as a linear function of batch size (the number of boards produced in one lot or batch). The intercept of this model is the:1) batch size2) unit variable cost3) fixed cost4) total cost5) total variable costQuestion 4 2 / 2 pointsIf x and y in a regression model are totally unrelated:1) the correlation coefficient would be -12) the coefficient of determination would be 03) the coefficient of determination would be 14) the SSE would be 05) the MSE would be 0sQuestion 5 2 / 2 pointsA manager wishes to predict the annual cost (y) of an automobile based on the number of miles (x) driven. The following model was developed: y = 1,550 + 0.36x.If a car is driven 10,000 miles, the predicted cost is:1) 20902) 38503) 74004) 69505) 5150Question 6 2 / 2 pointsA cost accountant is developing a regression model to predict the total cost of producing a batch of printed circuit boards as a linear function of batch size (the number of boards produced in one lot or batch), production plant (Kingsland, and Yorktown), and production shift (day and evening). In this model, “shift” is:1) a response variable2) an independent variable3) a quantitative variable4) a dependent variable5) a constantQuestion 7 2 / 2 pointsA multiple regression analysis produced the following tables:Predictor    Coefficients    Standard Error    tStatistic    p-valueIntercept    616.6849154.55343.9901080.000947×1    -3.338332.333548-1.430580.170675×2    1.7800750.3356055.304075.83E-05
