What is the overall mean speed of all the individuals ticketed by police?

To determine the overall mean speed of all the individuals ticketed by police, we need to consider how the mean is calculated. The mean speed is the total of all individuals' speeds divided by the number of individuals. If your answer is 67 mph, this suggests that the speeds of the individuals ticketed, when added together and divided by their number, yields this average.

The mean is sensitive to all values in the data set. If the mean is too high or too low compared to these values, it would reflect that there may be outliers or a skewed distribution. When calculating the mean speed, regardless of whether there are speed limits or variances in the types of vehicles, all ticketed speeds contribute to that mean.

This average would be reasonable if the distribution of speeds leaned towards a particular value, explaining why 67 mph is selected instead of any other options that imply a different central tendency of speeds observed. Typically, one would expect the mean to be slightly influenced by higher speeds if they are present, but without any extremes pushing the mean too high or low, 67 mph can be seen as a suitable representation of the data collected.

Overall, the mean speed effectively summarizes the average behavior of all ticketed drivers, which gives
