a.) k= c b.) k≠c c.) k> c d.) k< c Ans: b When testing the null hypothesis H0:βk= cagainst the alternative hypothesis H1:βk≠ c, We reject the null hypothesis if t≤t(1-α;N-2)or t≥t(1-α;N-2), which is equivalent to |t| ≤t (,N-2)
11.) In testing H0: 2= c using a .05 probability of a Type I error, you find a p-value of .38. What should you conclude? 12. You want to test the hypothesis H0: (c11+ c22) –c0= 0 and H1: (c11+ c22) –c0≠0 What test statistic should you use for the test? )(221102211bcbcsecbcbct)(22112211bcbcsebcbct)(2121bsebsebbt
13. When should a left-tailed significance test be used?
