An auto shop wants to examine the proportion of customers that have to return after an appointment. Last year, an examination of 381 customers found that 33.0% had to return after an appointment. You instituted some changes at the auto shop this year, and found from a sample of 258 customers that 36.2% had to return after an appointment. You want to conduct a hypothesis test to determine if there has been an increase in the proportion of customers that need to return after an appointment since the past year, with a = 0. 10. Using this information, what is the p in your analysis? Round your final answer to two decimal places. Note: 1- Enter your final answer with 2 decimal places.
