Question:
We measure the speeds of a sample of cars on some highway. We would like to conduct a hypothesis test to determine whether there is evidence that the true mean speed is greater than 100 km/h. The mean speed of the drivers in our sample is calculated to be 103 km/h. The P-value of the appropriate hypothesis test is calculated to be 0.20. What is the interpretation of this P-value?
