Out of 200 randomly selected people who rode a jet ski, 93.5% wore life vests. Out of 500500 randomly selected boaters, 88.8% wore life vests. Using a 0.05 level of significance, test the claim that the proportion of people who wear life vests while riding a jet ski is not the same as the proportion of people who wear life vests while riding in a boat. Let jet skiers be Population 1 and let boaters be Population 2.
