A publisher reports that 30% of their readers own a particular make of car. A marketing executive wants to test the claim that the percentage is actually more than the reported percentage. A random sample of 200 found that 38% of the readers owned a particular make of car. Is there sufficient evidence at the 0.01 level to support the executive's claim? Step 2 of 7: Find the value of the test statistic. Round your answer to two decimal places.
