A basketball enthusiast collected data on the scoring statistics of the 2018-2019 Golden State Warriors. He wanted to know if he could use Field Goals Made (FGM) to predict Free Throws Made (FTM). He ran a regression analysis and created the following regression equation and supplementary material. Assume that all the conditions are met. Parameter Std. Err. DF Intercept 0.28903828 15 Slope 0.065672563 15 Predicted Free Throws = -0.3604 + 0.4833(Field Goals) a) Interpret the slope of the regression equation....

Use the following for question 8 to 10. Silicon-germanium alloys have been used in certain types of solar cells. Researchers investigated how germanium (Ge) concentration affected the Fermi level position (eV). Assume all observations are independent. We have the following results. Simple linear regression results Dependent Variable : Fermi level Independent Variable : Ge Fermi level = 0.721786 - 0.43268475 Ge Sample size : 13 R (correlation coefficient) = -0.073757327 R-sq = 0.80156604 Estimate of error standard deviation = 0.073757327...

A movie analyst wants to predict revenue ("revenue") in $millions using the length of the movie in minutes ("runtime") and the budget of the film ("budget") in millions of dollars. A multiple linear regression model, where Y = revenue, X1 = runtime, and X2 = budget, has been fit. The output, with some missing values shaded, is displayed below.

Many movies are released each year and it would be interesting to be able to predict the Total Gross Revenues (in $1,000,000) from the box office based on a few predictors. The following predictors have been identified for 70 movies: BUDGET: Estimated budget in $1,000,000 LENGTH: The length of each movie in minutes SCREENS: Number of Screens on Opening Weekend AWARDS: Number of Award nominations of entire cast in their careers GENRE: Type of movie: Action, Comedy or Drama recoded...

2. Consider a study comparing is the length of time (in days) for recovery. The medications were randomly assigned to the patients. In group 1, the ni = 15 patients were given medication 1. In group 2, the n2 = 18 patients were given medication 2. We will use a simple linear regression model to analyse the recovery time according to the medication. We import the data with R and display a few two medications for severe bladder infections. The...
