You are doing research on balance and fitness. This research you will need a watch with a second hand.Identify a random sample of n = 12 men and n = 8 women.You must answer this question: How do you establish that this sample is truly random?

You will analyze your data and compute the following statistics for each group:

1) The Mean and standard deviation of the number of seconds the subject stayed balanced

2) The Median number of days per week exercised

3) The Mode of the favorite exercise

5) Construct a complete hypothesis test and determine if the two groups have significantly different balance using = 0.05.

create a one page introduction to your research, discuss how you selected your sample (is it a random sample?), and create one page conclusion.Present your data in an organized manner.
