In: Statistics and Probability
Use 2 separate groups to create two population mean estimates. Ask a group of friends how much time (in hours) they spent on social media throughout the previous day. Divide this group into two subgroups, and calculate the mean and standard deviation for both. Use the appropriate formula to construct a confidence interval to estimate the population mean. Then develop a main response in which you address the following:
hours per day on social media:
Group 1: 3 hours, 7 hours, 5 hours, 5 hours
Group 2: 6 hours, 4 hours, 2 hours, 5 hours
