Jill is calculating the standard deviation for her test grades. mrs. brown tells her that she did not take into account the curve on any of her grades and she needs to add 5 points to each grade. what is her new standard deviation? a) -2.204 b) 3.304 c) 5.804 d) 8.304

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
