Homework Answers
a)
| Age | Cholestrol |
| 49 | 55 |
| 27 | 45 |
| 52 | 40 |
| 38 | 57 |
| 44 | 28 |
For each pair (x,y) plot or use excel /softwarre directly
right graph is correct
b)
r = correl(age, cholestrol)
= -0.13223
= -0.132
c)
linear correlation is close to 0
so there does not exist any linear relationship
