The accompanying scatterplot shows the average teacher pay and the per pupil expenditure for 45 states out ol the 50 states and the District of Columbia. The regression equation is also shown. Complete parts (a) through (d) below. K Click the icon to view the scatterplot at average teacher pay and per pupil expenditures. a. From the scatterplot. is the correlation between average teacher pay and per pupil expenditure positive, negative. or near zero? The correlation is positive, because the scatterplot shows that as average teacher pay increases, the average per pupil expenditure tends to increase, and the regression line has a positive slope. be What is the slope of the regression equation? Interpret the slope in the context of the problem. Select the correct choice below and ll in the answer boxes to complete your choice. (Type integers or decimals, Do not round.) A- The slope is . For each additional $1 in average per pupil expenditure in a state, the average teacher pay increases by an average of 3 \"V B. The slope is 0.320 t For each additional $1 in average teacher pay in a state, the average per pupil expenditure increases by an average of 3 0.320 . c. What is the intercept of the regression equation? Interpret the yintercept or explain why it would be inappropriate to do so for this problem. Select the correct choice below and ll in the answer box(es) to complete your choice. O A- The intercept is . A state with an average teacher pay of $0 would have a predicted average per pupil expenditure of $ , on average. (Type integers or decimals, Do not round.) X Average teacher pay and average per pupil expenditure O 3- The intercept is . A state with an average per pupil expenditure of $0 would have a predicted average teacher pay of $ . on average. (Type integers or decimals. Do not round.) O c- The intercept is . It is not appropriate to interpret the intercept. because it is not possible to have an average teacher pay of $0, 2600 Avg per Pupil s = 537a+ 0320 Avg Teacher Pay ' Q (Type an integer or a decimal.
