Question 1: T-Test (35 points) A gerontologist was interested in whether men tend to show signs of Alzheimer's disease at an earlier age than women do. Following are the ages of onset of Alzheimer's disease for a sample of men and women (F)(X1) F Women (F)(X2) (F)(X2) Men X1 F (F)(X1) Age 60 2 65 2 70 3 75 2 80 1 N-10 (F)(XI) - X2 Age 60 65 70 75 80 1 1 1 3 4 Ν- 10 Σ(F)(X2) EF(XI) - ΣF(X2) (1) Fill out all blank cells in the table N (2) Find the means for both groups: - for men for women IF(X) N (3) Find variances for both groups and shown your work at each step: S Variance for men Variance for women:

(4) Find the standard error of the difference between means. Please use the calculation formula "the standard error of the difference between means" posted for week 17 (see Tables and Formulas) on T Test and show your work at each step Answer: (5) Find t value (obtained calculated) X-X 5X;-X3 Answer: (6) Find the value in the table with df-NI + N2-2, alpha-05. Please use the Table posted on Weck 17 and plug in the I valus from the table below T value (table) Indicate the locations of computed T value and table value on the bell curve. You will not need to mark the values on this place for draw a table of your own and mark the values will help you to determine which value - from the table or comprised is greater
