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)?

The minimum wage in washington has been increasing over the last ten years. years 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 washington state minimum wage $6.50 $6.72 $6.90 $7.01 $7.16 $7.35 $7.63 $7.93 $8.07 $8.55 $8.55 a) find the linear regression equation for the minimum wage in washington using this data ( x  0 in 2000). round to the thousandths. b) what is the slope? specifically, what does the slope represent in the real world context? c) what is the y-intercept? specifically, what does the y-intercept represent in the real world context? d) write your equation as a function of x. e) if you do not earn a college degree and you are earning minimum wage in 2020, what do you predict you will be earning per hour with the linear regression equation? f) if the trend continues, when will the minimum wage be $15 an hour? 3. why are your answers to #1d and #2a above different? which do you think is more accurate (#1 or #2) and why
