I really don't understand this part. The red is my work but I'm not even sure if it's correct and number 14 I have no clue how to work it

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)(12.26)~2/ (127+182)-2 = 12.9 V 127 + 182/ (127)(182) = 0.11 V10.66-2 / 127 + 14.26 2 / 182=1.42 14. Would your decision have been different if alpha were set at .01 (1 pt)
