Question

How to construct 6 confidence intervals -How you have to set up hypothesis test (One tail or two tail test) ?

Answer 1

Hypothesis testing consists of setting up two contradictory hypotheses, collecting sample data, determining the correct distribution, analyzing the data, making a decision, and writing a conclusion. For constructing 6 confidence intervals, you would need to go through these steps 6 times. The choice between one-tail or two-tail tests depends on the specific research question and the alternative hypothesis.

Step-by-step explanation:

Hypothesis testing consists of two contradictory hypotheses or statements, a decision based on the data, and a conclusion. To perform a hypothesis test, a statistician will do the following:

1. Set up two contradictory hypotheses.
2. Collect sample data. In homework problems, the data or summary statistics will be given to you.
3. Determine the correct distribution to perform the hypothesis test.
4. Analyze sample data by performing the calculations that ultimately will allow you to reject or decline to reject the null hypothesis.
5. Make a decision and write a meaningful conclusion.

For constructing 6 confidence intervals, you would need to have 6 different samples and perform each of the steps mentioned above for each confidence interval. Regarding the setup of hypothesis tests, the choice between one-tail or two-tail tests depends on the specific research question and the alternative hypothesis. If the alternative hypothesis suggests a direction, a one-tail test is appropriate. If there is no specific direction suggested, a two-tail test should be used.
