Answer the following

9) The computed test statistic * 1 point 11) When do we commit a * 1 point falls within the rejection Type II error? region, what decision and conclusion can you make? O When we accept the null hypothesis when it is true. Reject Ho, There is no significant O difference between sample and O When we reject the null hypothesis population mean. when it is true. Reject Ho, There is a significant When we reject the null hypothesis O difference between sample and O when it is false. population mean. Accept Ho, There is no significant O When we accept the null hypothesis when it is false. O difference between sample and population mean. Accept Ho, There is a significant O difference between sample and 12) is the * 1 point population mean. average of the group characteristic. 10) What is a z-test? * 1 point Sample mean O Standard deviation probability calculations Population mean O Statistical test O Algebraic calculations variance O probability test
