Demographic Variables and TV Narrative
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, is the age (in years), is the number of years of education, and is income (in $1000s). The computer output is shown below.
The regression equation is S = 4.51 R-Sq = 34.8%
Analysis of Variance
-Refer to Eating Habits of Canadians. Use the printout to find a 95% confidence interval for the average beef consumption per family of three in 2005. What is the 95% prediction interval for the beef consumption per family of three in 2005? Is there any with the validity of the 95% confidence level for these intervals?
