Write out the full linear model including all dummy variables below. Don’t worry about estimating regression coefficients just yet. Feel free to abbreviate variable names so long as they are clearly distinguishable.
David's Landscaping has collected data on home values (in thousands of $) and expenditures (in thousands of $) on landscaping with the hope of developing a predictive model to help marketing to potential new clients. Data for 14 households may be found in the file Landscape. Click on the datafile logo to reference the data.
(NEED ANSWERS FOR C, D, and E)
c. Use the least squares method to develop the estimated regression equation (to 5 decimals).
d. For every additional $1000 in home value, estimate how much additional will be spent on landscaping (to 2 decimals).
e. Use the equation estimated in part (c) to predict the landscaping expenditures for a home valued at $575,000 (to the nearest whole number).
i need a simple linear regression equation for miles per gallon as the response variable and weight as the predictor variable.

In a accounting course, a linear regression equation was computed to predict the final exam score from the score on the midterm exam. The equation of the least-squares regression line was Y= 10 + 0.85X. Y represents the final exam score, and X is the midterm exam score. QUESTION: Suppose Allen scores 83 on the midterm exam. What would be the predicted value of his score on the final exam (assuming no extrapolation error)?arrow_forward
- The value of a sports franchise is directly related to the amount of revenue that a franchise can generate. The accompanying data table gives the value and the annual revenue for 15 major sport teams. Suppose you want to develop a simple linear regression model to predict franchise value based on annual revenue generated. d. Predict the mean franchise value (in millions of dollars) of a sports team that generates $250 million of annual revenue.

Data are collected from a sample of 30 days, and the number of applications recorded and completion time in hours is recorded. Attached below is the regression output. What is the value of the measured t-test statistic to test whether the amount of time depends linearly on the number of loan applications recorded?

- The relationship between number of beers consumed (x) and blood alcohol content (y) was studied in 16 male college students by using least squares regression. The following regression equation was obtained from this study: y = -0.0127 + 0.0180x. Suppose that the legal limit to drive is a blood alcohol content of 0.08.
