Question: You have made many measurements of the yield of cosmic rays in your detector in a specified time interval. These data have determined the mean

You have made many measurements of the yield of cosmic rays in your detector in a specified time interval. These data have determined the mean yield to a relative error of 10%. In order to reduce the relative error to 5%, you must make twice as many measurements, overall.

True or False

Riding in your car at constant speed, you are using a posted “measured mile” along with your watch to check the correctness of the car’s speedometer. You make a 2% measurement of the time to travel over the mile, so therefore your determination of the car’s speed will also be accurate to 2%. Assume no uncertainty in the length of the measured mile.
