Why do we NOT reject Ho? We
are testing at a=0.05
Homework Answers
Critical region :- At a=0.05 level with df=n-2=3 in 2 tail from t table ta/2=+- 3.182.
I.e we reject the null hypothesis if tcal< -3.182 or tcal >3.182
Decision:- tcal < ta/2 (i.e 0.345 <3.182)
So fail to reject the null hypothesis H0

Need help with stats true or false questions
Decide (with short explanations) whether the following statements are true or false a) We consider the model y-Ao +A(z) +E. Let (-0.01, 1.5) be a 95% confidence interval for A In this case, a t-test with significance level 1% rejects the null hypothesis Ho : A-0 against a two sided alternative. b) Complicated models with a lot of parameters are better for prediction then simple models with just a few parameters c)...
