Q:

# 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.

Accepted Solution

A:
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.
