A safety specialist was concerned about cars' speeds on a certain busy stretch of road. They randomly selected 21 cars and measured their speeds at the same point on the road. Each car was from a different time period and day, so the specialist is willing to consider the sample as representative. The speeds in the sample were strongly skewed to the left with a sample mean of x ˉ = 96.5 km/hr. There were also a few outliers.
