ANSWER:
Step 1 of 4
Given:
(a) The estimate of the intercept is given in the row "Constant" and in the column "Coef" of the given MINITAB output:
The standard error of the intercept is given in the row "Constant" and in the column "SE Coef" of the given MINITAB output:
The t-value corresponding to the intercept is then the t-value corresponding to the test with null hypothesis
