9 Predict the cholesterol level of someone who has the age of 35. (2 digits)

10 Predict the cholesterol level of someone at the age of 55. (2 digits)

Answer 1

By using MS EXCEL WE HAVE

1] DEPENDENT VARIABLE IS CHOLESTROL

2] INDEPENDENT VARIABLE= AGE

3] Y INTERCEPT=95.95

4] SLOPE COEFFICIENT= 2.196=2.20

5] PROPER TERMINOLOG OF R SQARED= COEFFICIENT OF DETERMINATION

6] R ^2=0.365

7] TOTAL SUM OF SQUARES= 4163.429

8] STANDARD ERROR= 23.003

9] REGRESSION EQUATION

Y(HAT)= 95.947+2.196*X

X=35

Y(HAT)= 95.947+2.196*35

Y(HAT)= 172.81

10] FOR X= 55

Y(HAT)= 95.947+2.196*X

Y(HAT)= 95.947+2.196*55

Y(HAT)= 216.73
