Problem set 4: use the following information to answer questions 13-14 (5 points total): The GSS 2020 measures the amount of hours individuals spend on the Internet per week. Men
use the Internet 27.24 hours per week (standard deviation = 10.66, N=127), while women use
the Internet 25.33 hours per week (standard deviation = 14.26, N=182), Please review pp. 255-
258 in CH08 and Chapter Exercise #7 is very helpful on page 277.
13. Test the research hypothesis that men use the Internet more hours than women, set alpha
at 05 (4 pts)? Please use the formula 8.5 on page 256 to calculate the estimated
standard error.
(127-1)(10.66)^2 + (182-1)(12.267 2/(127+182)-2 = 12.9
V127 + 182/ (127) (182) = 0.11
110.66 2 / 127 +14.262/182=1.42
14. Would your decision have been different if alpha were set at 01 (1 pt)?
