SCENARIO 9-1
Microsoft Excel was used on a set of data involving the number of defective items found in a random sample of 46 cases of light bulbs produced during a morning shift at a plant.A manager wants to know if the mean number of defective bulbs per case is greater than 20 during the morning shift.She will make her decision using a test with a level of significance of 0.10.The following information was extracted from the Microsoft Excel output for the sample of 46 cases:

-Referring to Scenario 9-1,if these data were used to perform a two-tail test,the p-value would be 0.042.

Quizplus · Accepted Answer

In a two-tailed test, the p-value represents the probability of observing a test statistic as extreme as, or more extreme than, the observed value under the null hypothesis. A p-value of 0.042 indicates that there is a 4.2% chance of observing such extreme results if the null hypothesis were true, which is a direct outcome of performing the test with the given data.
