question 84

Essay

A statistician wanted to determine if the demographic variables of age, education, and income influence the number of hours of television watched per week. A random sample of 25 adults was selected to estimate the multiple regression model: A statistician wanted to determine if the demographic variables of age, education, and income influence the number of hours of television watched per week. A random sample of 25 adults was selected to estimate the multiple regression model: where y is the number of hours of television watched last week, x1 is the age (in years), x2 is the number of years of education, and x3 is income (in $1,000). The computer output is shown below. Test the overall validity of the model at the 5% significance level. What is the test statistic? F = ______________ ______________ Conclude that the model ______________ valid at the 5% level. Is there sufficient evidence at the 1% significance level to indicate that hours of television watched and age are linearly related? What is test statistic? t = ______________ ______________ Conclude that there ______________ sufficient evidence at the 1% significance level to indicate that hours of television watched and age are linearly related. Is there sufficient evidence at the 1% significance level to indicate that hours of television watched and education are negatively linearly related? What is the test statistic? t = ______________ ______________ Conclude that there ______________ sufficient evidence at the 1% significance level to indicate that hours of television watched and education are negatively linearly related.
