In question 1 : below annova table coefficients would be given and alpha might be -0.00012 and it might not be significant as it is falling in the shaded area when you drwa normal distribution diagram by using t table which means null is accepted which is alpha is not significantly different from 0
in question 2 : t statistic for slope is quite big and rejecting it is not easy and it comes beyond the shaded range which means slope is significantly different from 0
