question 95

Multiple Choice

TABLE 9- 1
Microsoft Excel was used on a set of data involving the number of parasites found on 46 Monarch butterflies captured in Pismo Beach State Park. A biologist wants to know if the mean number of parasites per butterfly is over 20. 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 Monarch butterflies:

$\begin{array}{llcc}\hline\bar{n}=46 ; \text {Arithmetic Mean} =28.00 ; \text {Standard Deviation} =25.92 ; \text { Standard Error}=3.82 ; \\\text {Null Hypothesis:} H_{0}: \mu \leq 20.000 ; \alpha=0.10 ; d f=45;\text { T Test Statistic }= 2.09;\\\text { One-Tailed Test Upper Critical Value} = 1.3006;\text { p-value} = 0.021; \text { Decision = Reject} \\\hline\end{array}$

-Referring to Table 9-1, what critical value should the biologist use to determine the rejection region?

• A) 0.6800
• B) 1.3006
• C) 1.3011
• D) 1.6794
