Two groups of children were given a set of coins (penny, dime, nickel, quarter, and half dollar) and asked to choose one of the coins. There were 67 children from the low income group of which 13 drew a nickel and 56 children from the high income group of which 18 drew a nickel. Using the p-value method, test the claim that the proportion of children from the low income group that drew a nickel is greater than the proportion of the high income group that drew a nickel at the 0.05 significance level.
