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%
