Nationwide, suppose that drinking water samples have probability 0.04 of having insufficient levels of chlorine. Suppose further that a recent study in alberta showed that 12 of 500 drinking water samples had insufficient levels of chlorine. Does this evidence imply that alberta is significantly under the national average? Test at a 5% significance level and report a p-value.
