TABLE 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 Table 9-1, the null hypothesis would be rejected.

-Referring to Table 9-1, the null hypothesis would be rejected.

Quizplus · Accepted Answer

The p-value of 0.034 is less than the level of significance of 0.10, so the null hypothesis (mean number of defective bulbs per case is less than or equal to 20) would be rejected in favor of the alternative hypothesis (mean number of defective bulbs per case is greater than 20).
