Explanation / Answer

The statistical software output for this problem is:

Simple linear regression results:
Dependent Variable: Shoe Size
Independent Variable: Height
Shoe Size = -17.288889 + 0.38888889 Height
Sample size: 10
R (correlation coefficient) = 0.84638896
R-sq = 0.71637427
Estimate of error standard deviation: 0.63574104

Parameter estimates:

Analysis of variance table for regression model:

Hence,

The regression equation will be:

Shoe size = -17.3 + 0.389 Height

Option B is correct.
