Chapter 10.5, Problem 16BSC
Appendix B Data Sets. In Exercises 13-16, refer to the indicated data set in Appendix B and use technology to obtain results.
16. Full IQ Score Refer to Data Set 7 “IQ and Lead" in Appendix B and find the best regression equation with IQ FULL (full IQ score) as the response (y) variable. Use predictor variables of IQ VERB (verbal IQ score) and IQ PERF (performance IQ score). Why is this equation best? Based on these results, can we predict someone’s full IQ score if we know their verbal IQ score and their performance IQ score? Is such a prediction likely to be very accurate?

We expect a car's highway gas mileage to be related to its
city gas mileage (in miles per gallon, mpg). Data for all
1259 vehicles in the government's 2019 Fuel Economy
Guide give the regression line
highway mpg = 8.720 + (0.914x city mpg)
for predicting highway mileage from city mileage.

(b) What is the intercept? Give your answer to three
decimal places.
intercept:
Why is the value of the intercept not
statistically meaningful?
The value of the intercept is an average value
calculated from a sample.
The value of the intercept represents the predicted
highway mileage for city gas mileage of 0 mpg,
and such a prediction would be invalid since 0 is
outside the range of the data.
The value of the intercept represents the predicted
highway mileage for slope 0.
O The value of the intercept represents the predicted
city mileage for highway gas mileage of 0 mpg,
and such a car does not exist.

Zagat restaurant guides publish ratings of restaurants for many large cities around the world. The restaurants are rated on a 0 to 30 point scale based on quality of food, decor, service, and cost. Suppose the regression equation that predicts the cost of dinner using the rating of the quality of food for the restaurants in a particular city is (cost of dinner) = 3.64*(food quality) + 2.77. If a restaurant in the city was given a Zagat rating of 27 and the average cost of dinner there is $74.35, what is the residual?
Question 4 options:

Explain whether each scenario is a classification or regression problem, and indicate whether we are most interested in inference or prediction and why. Finally, provide n (number of observations) and p (number of predictors):
1. Season ticket holders (STH) are important for both collegiate and professional sports teams. Penn State’s football program wants to use quantity of tickets, section, percentage of tickets used throughout the year, and percentage of games attended to predict whether a STH is likely to renew their seats. They currently have 4,000 STHs.

- RequiredPage 92 The company uses the number of professional hours as the cost driver for office support costs. Use an algebraic equation to describe how total office support costs can be estimated. Use a spreadsheet program to perform a regression analysis. Use office support costs as the dependent variable (Y) and the professional hours as the independent variable (X). Determine the total fixed cost per office and variable cost per professional hour. Identify the R2 statistic provided by the Excel program and explain what it means. Mr. Dean plans to open a new branch office in a Dallas suburb. He expects that the monthly professional hours will be 3,000. Estimate the total office support cost for Mr. Dean.
