what would happen to the mean, median, and mode values that you calculated ,if you added one player to the team whose points per game for the season was 25. just tell me if the mean, median, and mode would go up, down, or stay the same. Give an example of variable for which the mean would not be appropriate to describe the data (that is, tell me a circumstance in which you would not want to use the mean to describe a dataset)

Statistics teacher realize that his students keep using cell phones during the class. Then he did some research and found out that people use cell phones for 7.2 hours per day on average, and usage time variability around that average is 2.0449. Then he decides to give an assignment of reading books as an alternative of cell phone usage in exchange of 50 extra credit to their statistics exam. After the exam, he collected the data of cell phone usage time from his 127 students and calculated the average cell phone usagetime drops to 6.8 hours per day. a) Under the assumption that probability of uncontrolled factors leading you the wrong statistical decision is five percent, conduct the statistical analysis to decide wheter decrease in the cell phone usage time is real or it happens just because of the random chance b)and interpret the results
