(c) What is the R-Square, R-adjusted and F-stat for this regression? R - Square = 0.57 Adjusted R Square = 0.56 (d) Do a 2-sided t-test on B1 at the significance level of 0.05. Step1: Ho: B1 = 0 Ha: 1 # 0 Step 2: T = 1 - = 0.3517 se ( b1 ) 0.1057 = 3.3273 Step 3: df = 102 - 2 - 1 = 99 P = t(3.3273,99) = 0.0012 Step 4: P
