A well respected wild life researcher recently conducted a study of wild Jackalopes. He trapped and weighed 60 adult
wild Jackalopes in an attempt to gauge their health. As a
population, if a species loses weight it could be a signal
that the health of the population is in danger. Research conducted 10 years prior found that the population mean was 69.9 pounds. Test the claim that population mean of wild Jackalopes is equal to 69.9 lbs. Use a significance level of .01.

You have recently been notified by the US Fish and Wildlife Service that grants are available to help reestablish wild populations of Jackalopes if their health is in danger. These grants could total several millions of dollars for research. Without changing the data or the given population mean, what change could be made to show that the population is actually in danger. Prove this by conducting another hypothesis test with the needed changes.

Claim: _

Null Hypothesis: _

Alternative Hypothesis: _

Test Statistic: (state the statistic and find it’s value):

Find the pvalue for the given test statistic: _

At the 0.01 significance level would you reject the null or fail to reject the null? Justify your answer.

What final conclusion could you draw from your research? What will your report to the US Fish and Wildlife Service say?
