Spring is a peak time for selling houses. The file SpringHouses contains the selling price, number of bathrooms, square footage, and number of bedrooms of 26 homes sold in Ft. Thomas, Kentucky, in spring 2018 (realtor.com website) Click on the datafile logo to reference the data. DATA file a. The Excel output for the estimated regression equation that can be used to predict the selling price given the number of bathrooms, square footage, and number of bedrooms in the house: SUMMARY OUTPUT Multiple R R Square Adjusted R Square Standard Error Observations ANOVA Regression statistics Regression Residual Total Multiple R R Square ANOVA Adjusted R Square Standard Error Observations 0.7429 0.5519 0.4907 61948.6931 Regression statistics Regression Residual Total df Intercept Sq Ft Beds Lower 95% 0.9353 -145129.5298 Intercept Baths 0.9528 -49383.5243 0.0180 Sq Ft Beds 0.0326 Does the estimated regression equation provide a good fit to the data?

The accompanying scatterplot shows the average teacher pay and the per pupil expenditure for 45 states out of the 50 states and the District of Columbia. The regression equation is also shown. Complete parts (a) through (d) below. Click the icon to view the scatterplot of 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. b. What is the slope of the regression equation? Interpret the slope in the context of the problem. Select the correct choice below and fill in the answer bg (Type integers or decimals. Do not round.) Average Teacher Pay and Average Per Pupil Expenditure O A. The slope is For each additional $1 in average per pupil expenditure in a state, the…
The price of a previously owned Malibu car depends upon factors such as model year, mileage and condition. We want to investigate the relationship between a car's mileage and sale price for 30 sales. Use Data CHEV8. Draw a scatter plot of the data and comment on the relationship between the two variables. Determine the regression equation that best describe the relationship. Interpret the slope of the regression equation. Test for a significant relationship, using a = 0.05. Show all steps Construct a 98% confidence interval for the slope. Estimate the price of a Malibu car that has been driven for 85000 miles. Would you pay this price? Construct 99% confidence interval for the average price of a Malibu car that has 85000 miles
