A study was performed to determine the percentage of people who wear life vests while out on the water. A researcher believed that the percentage was different for those who rode jet skis compared to those who were in boats. Out of 200

randomly selected people who rode a jet ski, 94.5% wore life vests. Out of 500 randomly selected boaters, 89.8% wore life vests. Using a 0.01

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.

Compute the value of the test statistic. Round your answer to two decimal places.
