Question

emilio works for the parks department of west palm city. he tracked how many emails the mayor received about the citys parks each day last month. this box plot shows the results. what percent of the time did the mayor receive between 25 and 50 emails?

Explanation:

Step1: Recall box - plot properties

In a box - plot, the box represents the inter - quartile range (IQR), which contains 50% of the data. The lower quartile (Q1) is the value at the start of the box and the upper quartile (Q3) is the value at the end of the box. The median is the line inside the box. Also, the whiskers extend to the minimum and maximum non - outlier values.

Step2: Identify quartile values from the box - plot

Assume that 25 is close to the lower quartile (Q1) and 50 is close to the upper quartile (Q3) of the box - plot. Since the data between Q1 and Q3 represents the inter - quartile range, and the inter - quartile range contains 50% of the data.

Answer:

50
