Question

in a study of cyclists, you randomly sample the speed of 60 cyclists and find their average speed to be 12.5 mph. which statement is accurate? you conclude that the average speed of all cyclists is exactly 12.5 mph. you conclude that the average speed of all cyclists on this route is close to 12.5 mph. you conclude that the speed of more than half of the cyclists on this route is greater than 12.5 mph. you conclude that the speed of all cyclists on this route is exactly 12.5 mph.

Explanation:

A sample mean is an estimate of the population mean. We cannot say the population mean is exactly equal to the sample mean. Also, we have no information to conclude about the speed of more - than half of the cyclists. The sample mean gives an indication that the population mean (average speed of all cyclists on the route) is likely close to the sample mean.

Answer:

You conclude that the average speed of all cyclists on this route is close to 12.5 mph.
