Does it make sense to perform a hypothesis test if the primary goal is to obtain a confidence interval estimate? Why or why not?

Expert Solution

No,it make sense to perform a hypothesis test if the primary goal is to obtain a confidence interval estimate....because

the primary purpose or goal is to determine whether there is enough statistical evidence in favor of a certain belief..that is hypothesis testing forms a critical part and we have to reject or accept null hypothesis on the basis of critical value and test statistic...that is our primary goal..

You will perform a Chi-Square test test. For the hypothesis test make sure to report the following steps: Identify the null hypothesis, Ho, and the alternative hypothesis, Ha. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. Find the critical value(s) and identify the rejection region(s). Find the appropriate standardized test statistic. If convenient, use technology. Decide whether to reject or fail to reject the null hypothesis. Interpret the decision in the context of the original claim. A sports...
