The manager of a commuter rail transportation system was recently asked by her governing board to determine which factors have a significant impact on the demand for rides in the large city served by the transportation network. The system manager collected data on variables thought to be possibly related to the number of weekly riders on the city's rail system. The file P10_20.xlsx contains these data. Estimate a multiple regression equation using the given data. Interpret each of the estimated regression coefficients. Enter your answers in thousands. For example, an answer of 1.234 thousand should be entered as 1.234, not 1,234. Round your answers to three decimal places, if necessary. Holding all else constant, ridership by approximately thousands when the price per ride rises by $1.00.

A car dealer wants to estimate the price of a used car based on the age of the car and the mileage. Based on a sample of 20 cars, she determines the sample regression equation that predicts price taxes on the basis of the age (in years) of the number of miles is Price=21,510-1230Age-0.035 Miles (a) If the age of the car was fixed and the mileage was increased by 10,000, would the price increase or decrease and by how much? (b) Predict the selling price of a five-year-old car with 65,000 miles. (Round your answers to the nearest whole number.)
For ease of performing the next task, move the variable "Social Networks - Facebook, Twitter, etc" to column A on the spreadsheet. (i.e. Make sure it is the first column in the spreadsheet.) The hiring managers recognize that the funding for one employment source depends on the funding for the other sources. Therefore, they want you to perform a multiple regression predicting Social Network funding from Months 1-12, while controlling for the funding of Billboard, Careerbuilder, Company Intranet - Partner, and Diversity Job Fair. Assume that we know the funding for the the controlled variables for Month 13. They are: Billboard: 520 Careerbuilder: 800 Company Intranet: 0 Diversity Job Fair: 1000 For this model and these known values, what is the predicted value for Social Network funding for Month 13?
A medical researcher wants to determine how a new medication affects blood pressure. An amount of medication of 145 mg is found to result in a blood pressure of 128.42 mm Hg. What is the predicted blood pressure? Where is the observed value in relation to the regression line? The equation of the regression line is �^=140+(−0.0667)�. Where is the observed value in relation to the regression line? An amount of medication of 178 mg is found to result in a blood pressure of 128.13 mm Hg. What is the predicted blood pressure? Where is the observed value in relation to the regression line? An amount of medication of 200 mg is found to result in a blood pressure of 129.15 mm Hg. What is the predicted blood pressure? The options for the drop down boxes are below, above or on the regression line.
The table below gives the age and bone density for five randomly selected women. Using this data, consider the equation of the regression line, yˆ=b0+b1xy^=b0+b1x, for predicting a woman's bone density based on her age. Keep in mind, the correlation coefficient may or may not be statistically significant for the data given. Remember, in practice, it would not be appropriate to use the regression line to make a prediction if the correlation coefficient is not statistically significant.

A business statistics professor would like to develop a regression model to predict the final exam scores for students based on their current GPAs, the number of hours they studied for the exam, the number of times they were absent during the semester, and their genders. The data for these variables are given in the accompanying table at the bottom of this page. a) Using Excel, construct a regression model using all of the independent variables. Create the dummy variable Gen, which equals 1 for a male and 0 for a female student ( this assignment is arbitrary) complete the regression equation for the model below, where y= Score, x1= GPA, x2= Hours, x3= Absenses, and x4= Gen. y= (__) + (__)x1 + (__)x2 + (__)x3 + (__)x4 b) Test the significance of the overall regression model using a= 0.10. c) interpret the meaning of the regression coefficient for the dummy variable. d) using the p-values, identify which independent variables are significant with a= 0.10. e) construct a regression…
