Explanation / Answer

The statistical software output for this problem is:

Simple linear regression results:
Dependent Variable: y
Independent Variable: x
y = 1 + 2.1 x
Sample size: 5
R (correlation coefficient) = 0.97913005
R-sq = 0.95869565
Estimate of error standard deviation: 0.79582243

Parameter estimates:

Analysis of variance table for regression model:

Hence,

a) Option C is correct.

b) Option D is correct.

c) From regression output,

SSE = 1.9
