Worked Solution & Example Answer:A travel agent records the duration and cost of the 15 flights he sold on one day - OCR - GCSE Maths - Question 1 - 2020 - Paper 6
Step 1
Duration 210 minutes
Answer
To plot the flight with a duration of 210 minutes, locate the 210 mark on the X-axis of the scatter diagram. For the cost of £130, identify the corresponding position on the Y-axis. Mark the point at (210, 130) on the scatter plot.
For the second flight with a duration of 1 hour 40 minutes, first convert this to minutes: 1 hour 40 minutes = 100 minutes. On the scatter diagram, find the 100 mark on the X-axis and the cost of £80 on the Y-axis. Plot the point at (100, 80) on the scatter plot.
Step 2
Circle the most likely flight
Answer
After analyzing the scatter plot, the most likely flight that was discounted could be identified as the point that represents a cost significantly lower than what is otherwise expected at its duration. Considering the other plotted points, circle the point that has an outlier cost that seems inconsistent with the general trend.
