A survey found that the daily time spent on social media differs by age group. You select samples of people from each age group to verify the information. The following table lists the difference of time spent by the groups ages 16 to 24 and 25 to 34 from the sample. a) Perform a hypothesis test using alpha 0.01 to determine if the average time spent differs by age group. Show computations. See formulas on page 434&435. b) Determine the p-value. Show computations. See formulas on page 437 c) Construct a 99% confidence interval. Show computations
