What does the CI tell us? Did we already see this coming when we tested for significance of beta?

Solve the following hypothesis test problems (hint: use the t-tables in the document "Formulas and Tables" as the reference guide for computing the critical value)

A. ) Sample size : 82 significance level : 59 Model : alpha + beta * * Alpha : 13.65 SE ( alpha ) : 4.45 Beta : 682 SE ( beta ) : 3.98 a ) Test for HO beta - 0 b ) Compute the confidence interval What does the CI tell us ? Did we already see this coming when we tested for significance of bela
