A report states that adults 18-years to 24- years-old send and receive 128 texts every day. In order to test this claim, we take a sample ofindividuals where we find the sample mean to be 118.20 texts per day (118.20). Assume a known population standard deviation of 33.17 texts per day (33.17).

A) Set up the null hypothesis () and the alternative hypothesis () - interpret each in terms of the business application.

B) At the 95% confidence level, use the "rejection region"approach to test whether the average number of texts per day is different than the one claimed in the report. Show all steps and calculations. C) At the 95% confidence level, use the "probability" approach test whether the average number of texts per day is different than the one claimed in the report. Show all steps and calculations. D) How do you interpret the results from parts (b) and (c)?
