Conduct a hypothesis test using a two-tailed t test with an alpha level of .05.  You need to compare the hours/week spent on social media in two groups of 16 people (under and over age 25), with the M=8.5 and the SS= 68 for people under 25 and the M=6.5 and SS = 52 for people over 25  Is there a significant difference between them? If there is, which group spent more time on social media?
