An automobile manufacturer has given its car a 57.7 miles/gallon (MPG) rating. An independent testing firm has been contracted to test the actual MPG for this car since it is believed that the car performs under the manufacturer's MPG rating. After testing 210 cars, they found a mean MPG of 57.5. Assume the population standard deviation is known to be 1.9. Is there sufficient evidence at the 0.02 level to support the testing firm's claim? Step 1 of 6: State the null and alternative hypotheses.
