(a) Test the claim that Sludge County has a pinworm infection rate that is greater than the national average. Use a 0.05 significance level.
(b) Test the claim that Sludge County has a pinworm infection rate that is greater than the national average. Use a 0.01 significance level.
(c) Why was it that you could make apparently contradictory statements in parts (a) and (b)?
