A rental car agency has 15 rental cars on its lot. The following table shows the mileage of each car. Use the data to complete parts a through d below. 19,138 11,478 18,237 10,992 8,596 6,812 14,026 6,355 4,127 11,801 4,132 16,252 15,812 13,923 19,122 a. Calculate the mean for this population. μ= (Round to one decimal place as needed.) b. Calculate the sampling error using the 5 cars in the first row as your sample. The sampling error for the first 5 cars is (Round to one decimal place as needed.) c. Calculate the sampling error using the 10 cars in the first two rows as your sample. The sampling error for the first 10 cars is (Round to one decimal place as needed.) d. How does increasing the sample size affect the sampling error?
