Question

my question is

Q. Discuss two alternative measures not used in this study to assess balance and fitness.

below is my project. please help answering above question to find what other two alternative measures are there that are not used in the study thank you in advance :)

You are doing research on balance and fitness. To complete 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? Have each subject perform the following task: a) Have the subjects stand with their hands at their side, raise one knee, cross their ankle over the other knee, squat and bring their hands palms together in front of their chest. Time the subject 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? 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 4) The 90% confidence interval of the mean 5) Construct a complete hypothesis test and determine if the two groups have significantly different balance using a= 0.05. Write a one page introduction to your research, discuss how you selected your sample (is it a random sample?), and write a one page conclusion. Present your data in an organized manner.

Answer 1

ANSWER

GIVEN THAT

Given sample of n=12 men

n=8 women

making the mean, SD, median, mode etc, without data , because the given question does not have the data , we cannot find mean and SD, median , mode, 90% C.I

Mean for man=$\frac{(0.22+0.20+---+0.20)}{12}$

$=\frac{2.58}{2}$

=0.2150

Mean for women$=\frac{(0.20+0.21+---+0.25)}{8}$

1.83 8

=0.2288

Standard deviation for men $=\sqrt{\frac{1}{2}\sum_{i=1}^{12}\left ( X_i-\bar{X} \right )^2}$

$=\sqrt{\frac{1}{12}(0.0061)}$

= 0.0235

Standard deviation for women $=\sqrt{\frac{1}{2}\sum_{i=1}^{12}\left ( X_i-\bar{X} \right )^2}$

$=\sqrt{\frac{1}{18}(0.0055)}$

=0.0280

2) The median number of days per week exercise for men is 3 and women is 2.5

3) Mode for the favorite excercise for men is aerobics and for women is Aerobics and cardiovasculas

4) the 90% confidence Interval is mean for men is (0.20,0.23)

the 90% confidence Interval is mean of women is (0.205,0.252)
