Answer:
Alternative C is correct;
Yes, there is evidence at the 5% significance level
Explanation:
To determine whether a linear relationship does exist between shoe size and height, we shall simply be testing the null hypothesis;
β=0
against the alternative;
β≠0
From the output, the p-value of the coefficient of height is given as 0.042 or equivalently 4.2%
Since the p-value, 4.2% is less than 5% level of significance we reject the null hypothesis that claims no linear relationship exists between the shoe size and height.
