Answer 1

@DanJS hey can you help?

Answer 2

@triciaal

Answer 3

what is the correlation coefficient?

Answer 4

uum, i dont know

Answer 5

sorry phone

Answer 6

let us find the slope

Answer 7

change in y / change in x = y2 -y1/ x2 -x1 for 2 points on the line (x1,y1) and (x2, y2)

Answer 8

what do i put in for x and y?

Answer 9

give me a min stats not my best let me verify correlation

Answer 10

okay

Answer 11

the slope is for the "best fit" line

Answer 12

okay

Answer 13
