Old McDonald had a farm and for the last six years she has measured the amount of rainfall that her soybean crops recieved over the course of the growing season. She wanted to know if the amount of rainfall in the growing season was a good predictor of the amount of soy bean crop yield she grew. Below is the data from the last six seasons of growing

Season	1	2	3	4	5	6
Average rainfall (in)	23	19	24	17	20	16
Crop Yeilds (kilotons)	18	11	19	11	15	13

Given: n = 6 SumX = 117 SumY = 87 SumXY = 1774 SumX² = 2411 SumY² =1321

a) what is the correlation coefficient (4 decimals)

b)interpret the a)

c) find coefficient of determination

d) interpret c)

e) is rainfall a good preditor of monthly sales?
