Explanation / Answer

a:

From the output the regression analysis we have

Dependent variable: width

b:

The explanatory variable: sex, length, footmeas, headedness

c:

p-value of length is less than 0.05 so it is significant to the model.

d:

The p-value of sec is 0.076 which is greater than 0.05 so it is not significant to the model. That is we can remove it from the model.
