3) A physical education director claims by taking a special vitamin, a weight lifter can increase his strength. Eight athletes are selected and given a test of strength, using the standard bench press. After 2 weeks of regular training, supplemented with the vitamin, they are tested again. Test the effectiveness of the vitamin regimen at a = 0.05. Each value in these data represents the maximum number of pounds the athlete can bench-press. Assume that the variable is approximately normally distributed. Athlete 1 2 3 4 5 6 7 8 Before (X₁) 210 230 182 205 262 253 219 216 After (X2) 219 236 179 204 270 250 222 216
