On the west side of town water was tested in a random selection of homes and of the 414 homes and 16 had high levels of lead while on the east side of town there were 228 randomly selected homes and 3 contained high levels of lead. Perform the significance test and determine the conclusion we could make at the 0.05 significance level. O Since the p-value > alpha, then we would fail to reject the null. We do not have convincing evidence that there is a difference in the proportion of homes that contain high levels of lead. Since the p-value alpha, then we would reject the null.
