Little brain teaser for you guys ;)

Select the item letter in Group II that represents best for each statement in Group I and write the selected letter at the end of the corresponding statement of Group I. Group I: Mean square error of an estimator: To test independence of two random variables: To predict a variable from other relevant variables: To compare annual income means of three or more states: Type II error in hypothesis testing: Type I error in hypothesis testing : Power of a test in hypothesis testing is relating to: If P-value= 0.001: Ratio of two sample variances is 4 (four): Group II: Regression analysis. Paired t test. Analysis of variance. Chi-square test Indicating the associated two variances are significantly different. Reject H0 when H0 is wrong. Reject Ho when Ho is right. Fail to reject H0 when H0 is wrong. Data strongly support the alternative. Data strongly deny the alternative. For identifying a sufficient statistic for unknown parameters. Lower bound for variances o
