Name: Keamon Sims Please complete the following assignment and submit your completed assignment to the assignment link on Moodle no later than Sunday, 11 :59 pm CST Note: You must show all work (each step) to receive full credit. 1. Calculate the standard error of the difference for each of the following sets of independent data. (10 Points): a--256, M-35, SD1-10.2-27.8. M2 = 35, SD2+ 11.9 b.-38.7, NI 65, SD1 17.4; 48.2, N2-58, SD2 16.7 2. What are the t values for problem la and lb? Is either significant? At what level of confidence?(10 Points): 3. A researcher compared the amount of valgus knee motion (distance in cm between the knees when landing from a vertical jump in high school female basketball players who regularly engaged in strength training versus those who did not strength train. The data were obtained using kinematic analysis. Smaller numbers mean more valgus motion. (20 Points) Trained subject Valgus motion (cm) Untrained subject Valgus motion (cm 32.7 27.9 34.3 39.4 Page 1 of 2 ! 563 words

Explanation / Answer

Solution:-
a. N1 = 35 ,SD1 = 10.2 , N2 = 35 , SD2 = 11.9
  
Standard error :- sqrt((SD1/N1)+(SD2/N2)) = sqrt((10.2/35)+(11.9/35)) = 0.7946

b. N1 = 65 ,SD1 = 17.4 , N2 = 58 , SD2 = 16.7
  
Standard error :- sqrt((SD1/N1)+(SD2/N2)) = sqrt((17.4/65)+(16.7/58)) = 0.7454
