(3 points possible) How many degrees of freedom are there in the following scenarios for a t- Test of Independent Samples: a. Sample 1: 48 boys, df=46 Sample 2: 73 girls, df= 71 b. Sample 1: 51 goats, df= 49 Sample 2: 32 train engineers, df= 30 c. Sample 1: 68 elderly, df=66 df= 45 Sample 2:47 individuals who can tie their own shoes, 2. (7 points possible) Use the following information to calculate the t-test obtained value. Then complete the t-Test fill-in-the-blank report below: X = 40 X2=38 n =20 n2=22 S = 36 S2 = 16 Fill in the three blanks to complete your written report of the t-Test you just ran. For determining the significance level use the two-tailed test at the 0.05 level: (__) = P___ .05 3. (3 points possible) Answer the following based on the degrees of freedom and obtain value you just found in question 2 above: A. What would be the critical value for a one-tailed test given the degrees of freedom above in question 2: a. @ .05 b. @ .01 B. Why, or why would you not, be able to reject the null hypothesis? 4. (3 points possible) What is the effect size for the following information? Is this considered a small, medium, or large effect size? X = = 18 X = 16 n = 60 n = 80 SD =8 SD2 = 6 (2 points) Effect Size: (1 point) Is this considered small, medium, or large?
