Question

8. Which box-and-whisker plot shows the high temperatures in Philadelphia, Pennsylvania, during the first two weeks of March: 39, 41, 33, 57, 34, 30, 47, 33, 49, 52, 32, 53, 37, 43 (1 point)

A.A box-and-whisker plot is shown above a number line that extends from 30 to 58 with 1 unit markings. The box extends from 33 to 49 with a division at 39. There is also a point marked at 39. The whisker on the left extends from 30 to 33. The whisker on the right extends from 49 to 57.
B.A box-and-whisker plot is shown above a number line that extends from 30 to 58 with 1 unit markings. The box extends from 33 to between 50 and 51 with a division at 41. There is also a point marked at 41. The whisker on the left extends from 30 to 33. The whisker on the right extends from between 50 and 51 to 57. C.A box-and-whisker plot is shown above a number line that extends from 30 to 58 with 1 unit markings. The box extends from 33 to 49 with a division at 40. There is also a point marked at 40. The whisker on the left extends from 30 to 33. The whisker on the right extends from 49 to 57.
D.A box-and-whisker plot is shown above a number line that extends from 30 to 58 with 1 unit markings. The box extends from 33 to between 50 and 51 with a division at 40. There is also a point marked at 40. The whisker on the left extends from 30 to 33. The whisker on the right extends from between 50 and 51 to 57.

I am saying this is D.

Answer 1

39, 41, 33, 57, 34, 30, 47, 33, 49, 52, 32, 53, 37, 43

Step 1: Order the data from least to greatest:

30, 32, 33, 33, 34, 37, 39, | 41, 43, 47, 49, 52, 53, 57
40
Find the median: 40 (use | to mark this on the box plot)
Find the lower and upper extremes: 30 and 57
Find the middles of the lower and upper halves (called lower and upper quartiles) (see bold): 33 and 49; This is where the box is formed.

These are the 5 numbers used to create the box plot.

Choice C uses these number to create the box plot.
