you are given the following data number of abscences 0,1,2,3,4,5 final grades 96,92,71,66,60,51 find the correlation coefficient for data find equation for the regression line for data and predict the final grade ofa student who misses 3.5 days
-------------------
r = -0.9755
Equation:
y = -9.3143x + 95.95
==========================
f(3.5) = 63.352
======================
Note: I used my TI-84 to find "r", the regression equation, and f(3.5).
