A researcher claims that college women use social media more than college men. She conducts a random sample of 17 college women and 14 college men and obtains the following summary: Women n1 =17 x̄=13.7 hrs S1=5.2 hrs Men n2=14 x̄=12.9 hrs s2=3.9 hrs Test the claim at the .05 significance level. Identify the null and alternative hypothesis, critical value, test statistic, P-value, the Decision regarding the hypothesis, and the final conclusions. Draw the Distribution.
