An auto shop wants to examine the proportion of customers that have to return after an appointment. Last year, an examination of 350 customers found that 34.7% had to return after an appointment. You instituted some changes at the auto shop this year, and found from a sample of 375 customers that 41.6% had to return after an appointment. You want to conduct an analysis to determine if there has been a change in the proportion of customers that need to return after an appointment since the past year, with a significance level of 10%. Using this information, what is the SE(Pcurrent year - Plast year) of your analysis? Round any intermediate numbers to four decimal places and choose the closest choice to your answer.
