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 300 randomly selected people who rode a jet ski. 91 % wore life vests. Out of 350 randomly selected boaters, 84 % wore life vests. Using a 0.02 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. Step 2 of 3: Compute the value of the test statistic Round your answer to two decimal places.
