Question
It is commonly believed that age is related to Internet usage among college students. Here are data from a sample of six college students:
Age (x)
Internet usage hours/week (y)
18
20
18
19
19
17
20
16
20
15
21
8
The goal is to perform the bivariate regression of age on Internet usage hours per week. Ultimately you’ll have to compute the values for B0 + B1 in this equation: Internet = B0 + B1Age + . If B0 = 78.23, B1 = -3.23, and the standard error for this slope is .70, what is the t-score for the null hypothesis that B1 = 0? Report the absolute value for the t-score.
between 3.5 and 4.5
more than 5.5
less than 2.5
between 4.5 and 5.5

Explanation / Answer
t = b1/Standard error
t = -3.23/0.70 = 4.614
Absolute value of the t- score lies between 4.5 and 5.5
