Question

The box plot represents the scores on quizzes in a science class. A box plot uses a number line from 70 to 86 with tick marks every one-half unit. The box extends from 76 to 80.5 on the number line. A line in the box is at 79. The lines outside the box end at 72 and 84. The graph is titled Science Quizzes, and the line is labeled Scores On Quizzes. Determine which of the following is the five-number summary of the data. Min: 72, Q1: 79, Median: 80, Q3: 82, Max: 84 Min: 75, Q1: 77.5, Median: 80, Q3: 81.5, Max: 85 Min: 72, Q1: 76, Median: 79, Q3: 80.5, Max: 84 Min: 73, Q1: 77, Median: 78, Q3: 80.5, Max: 85

It’s correct! I tried it! Thank u

Answer 2

The five-number summary of the data is the set of values that divide the data into four equal parts. It consists of the minimum, the first quartile (Q1), the median, the third quartile (Q3), and the maximum.

To find the five-number summary from a box plot, you can use the following steps:

The minimum is the leftmost point on the line outside the box. In this case, it is 72.

The first quartile (Q1) is the left end of the box. In this case, it is 76.

The median is the line inside the box. In this case, it is 79.

The third quartile (Q3) is the right end of the box. In this case, it is 80.5.

The maximum is the rightmost point on the line outside the box. In this case, it is 84.

Therefore, the correct answer is Min: 72, Q1: 76, Median: 79, Q3: 80.5, Max: 84.
