Exam 18: Multiple Regression

A sample of 33 companies was randomly selected and data collected on the average annual bonus, turnover rate (%), and trust index (measured on a scale of 0 - 100).In a multiple regression estimating turnover rate using average bonus and trust index, what is the correct null hypotheses for testing the regression coefficient of Trust Index?

Selling price and amount spent advertising were entered into a multiple regression to determine what affects flat panel LCD TV sales.The correct null and alternative hypotheses for testing the regression coefficient of Price is _______________________ .

A sample of 33 companies was randomly selected and a multiple regression model was performed using average annual bonus and trust index (scale of 0 - 100) to explain turnover rate.According to the output below, what is the F statistic to determine the overall significance of the estimated is ________________________ .

A sample of 33 companies was randomly selected and data collected on the average annual bonus, turnover rate (%), and trust index (measured on a scale of 0 - 100).Based on the output, how much of the variability in Turnover Rate is explained by the estimated multiple regression model?
