Question

two english classes with the same number of students took a final exam. the box - and - whisker plots below (sometimes called boxplots) summarize the test scores for each class. use the box - and - whisker plots to answer the questions. (a) a score above 70 is considered passing. which class had more passing scores? select (b) which class had the highest test score? select (c) which class had a higher median test score? select (d) which class had test scores with a larger interquartile range (iqr)? select

Explanation:

Step1: Analyze passing - scores

For Class A, the box - and - whisker plot shows that a significant portion of the data (more than half as the median is above 70) is above 70. For Class B, less than half of the data is above 70. So Class A has more passing scores.

Step2: Identify highest score

The end - point of the whisker represents the highest score. For Class A, the highest score is around 80. For Class B, the highest score is around 95. So Class B has the highest test score.

Step3: Locate median

The line inside the box represents the median. For Class A, the median is around 75. For Class B, the median is around 65. So Class A has a higher median test score.

Step4: Calculate IQR

The inter - quartile range (IQR) is the length of the box, which is Q3 - Q1. For Class A, Q3 - Q1 is relatively small. For Class B, Q3 - Q1 is larger. So Class B has a larger IQR.

Answer:

(a) Class A
(b) Class B
(c) Class A
(d) Class B
