Question
The scatterplot shows the percent of flights with delayed departures and the percent of flights with delayed arrivals, by departing airport, for 10 US airports in a certain one-year period. A line of best fit is also shown. For how many of the 10 airports was the percent of flights with delayed arrivals less than predicted by the line of best fit?
The correct answer is: 6
The points above the number line are flights with delayed arrivals and
The points below the number line are flights with delayed departure
The points above number line are 4 and below number line are 6.
The difference in points 6 – 4 = 2
