Daily average time people spend on their phones in hrs

-Make a histogram for each data set, stem and leaf for each data set and side by side box plots for each variable.

-Use a calculator to do a 5#summary for each data set, outlier calculations using the 5#summary for each data set. Write a brief comparison of the data sets using these values.

-Perform a hypothesis test(paired t-test or two-sample t-test, whichever applies) to see if there is a difference between your two groups. Include all parts of the test and write a conclusion. Be sure to include if you have met the assumptions.
