Previously you calculated the mean and standard deviation of the seven sample measurements to be x ̅ = 89.9 meters and s = 11.6 meters, respectively. Now the researchers want to know whetherσ^2, the variation in the population of trap-spacing measurements, is larger than 10 m2. They will conduct a test of hypothesis using α = 0.05.
a.) Note that s2 > 10. Consequently, a fisherman wants to reject the null hypothesis. What are the problems with using such a decision rule?
b.) Compute the value of the test statistic.
c.) Find the approximate p-value of the test
d.) Give the appropriate conclusion.
e.) What conditions must be satisfied for the test results to be valid?
