Answer :

Final answer:

To construct a box-and-whisker plot for the given data, arrange the data in ascending order and find the median, lower quartile, and upper quartile. Plot these values on a number line and draw a box and whisker to represent the data.

Explanation:

To construct a box-and-whisker plot for the given data, follow these steps:

  1. Arrange the data in ascending order: 310, 310, 310, 310, 320, 450, 460, 470, 500, 500, 505, 510, 520, 540, 580, 600, 650, 700, 700, 705, 705, 840, 870, 900, 1000, 1200, 1200, 1225, 1237.5, 1250, 1250, 1300, 1400, 1720, 2500, 3700, 3700, 3700, 3700, 3700.
  2. Find the median, which is the middle value of the data set. In this case, it is the 20th value, which is 705.
  3. Find the lower quartile, which is the median of the lower half of the data. In this case, it is the 10th value, which is 510.
  4. Find the upper quartile, which is the median of the upper half of the data. In this case, it is the 30th value, which is 1250.
  5. Plot the minimum value (310), the lower quartile (510), the median (705), the upper quartile (1250), and the maximum value (3700) on a number line.
  6. Draw a box, but the ends of the box at the lower quartile and the upper quartile, and draw a line (whisker) from the box to the minimum and maximum values.
