STEP 1: You are doing research on balance andfitness. To complete this research you will need a watch with asecond hand. Identify a random sample of n = 12 men and n = 8women. You must answer this question: How do youestablish that this sample is truly random?

STEP 2: Have each subject perform the followingtask:

1. Have the subjects stand with their hands at their side, raiseone knee, cross their ankle over the other knee, squat and bringtheir hands palms together in front of their chest. Time thesubject until they put their foot back down on the floor.

b) Ask the following questions:

                       i) How many days per week do they exercise?

                       ii) What is their favorite exercise?

STEP 3: You will analyze your data and computethe following statistics for each group:

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

2) The Median number of days per week exercised

3) The Mode of the favorite exercise

4) The 90% confidence interval of the mean

STEP 4: Construct a complete hypothesis testand determine if the two groups have significantly differentbalance using α = 0.05.

STEP 5: Write a one page introduction to yourresearch, discuss how you selected your sample (is it a randomsample?) and write a one page conclusion. Present your data in anorganized manner.
