 P: 297 1. The problem statement, all variables and given/known data I have used OLS and found that: b0 = 6,85 b1 = 3,88 with se= 0,1121 n = 20 Person x claims that b1 = 5 Choose an alternative hypothesis. Does your estimated relationship support this claim? Use a 5 % significance level 3. The attempt at a solution H0 = b1 = 5 H1 b1!= 5 t((1-a)/2,18) = 2,101 t = ($$\overline{x}$$ - h0)/se(b1) = (3,88 - 5)/(0.1122) = -9.99 t lies not in the interval +- 2,101 so I reject H0 Is this correct?
