can you check if i have correct these 2 questions
#1
find the outlier and tell how it affects the mean for:
13, 16, 12, 16, 3, 14
mean: 12.3
the outlier is: 3
mean without outlier: 14.2
THE OUTLIER LOWERS THE MEAN BY : 1.9

Your math is correct, except that the mean in both cases would be negative, and the outlier would increase the mean.
