Why are the results for both models different? What is the difference of the model? Why does it play a role?

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) 2.) Sample size: 32 significance level: 5% Model: y-alpha + beta*x Alpha: 23.56 SE(alpha): 11.02 Beta: 2.23 SE(beta): 1.87 a) Test for HO: beta=0 b) Test for HO: beta=3 3.)
