Unit 6 Discussion: Hypothesis Testing L Available until Apr 15, 2023 11:59 PM. Submission restricted after availability ends. In this discussion, you will be conducting a hypothesis test using the following scenario: In a study of store checkout scanners, 1234 items were checked for pricing accuracy, and 20 checked items were found to be overcharges. Use a 0.05 significance level to test the claim that when scanners are used, the number of items that are overcharged is greater than 1%. 1. State a claim from the above scenario in words. 2. State the null and alternative hypotheses. Be sure to use the correct notation. 3. Find the value of the appropriate test statistic. Be sure to include the correct type (e.g. z) and value. 4. Find the p-value. 5. State your conclusion about the null hypothesis. 6. State your conclusion about the claim. Unit 7 Discussion: Correlation and Regression Available until Apr 29, 2023 11:59 PM. Submission restricted after availability ends. 1. Give an example of two variables that you would expect to have a correlation close to Unit 6 Discussion: Hypothesis Testing L Available until Apr 15, 2023 11:59 PM.
