Question

last year, greg got a new job managing the gift shop at the bern valley zoo. one of his responsibilities was to track the shops total sales each day. this box plot shows the results. gift shop sales ($) what percent of the time did the gift shop have sales of $350 or less? %

Explanation:

Step1: Recall box - plot properties

In a box - plot, the box represents the inter - quartile range (IQR). The left - hand side of the box is the first quartile ($Q_1$), the line inside the box is the median ($Q_2$), and the right - hand side of the box is the third quartile ($Q_3$). The whiskers extend to the minimum and maximum values within 1.5 times the IQR of the quartiles.

Step2: Identify the position of $350$ on the box - plot

The value of $350$ is at the third quartile ($Q_3$) of the box - plot.

Step3: Use quartile percentage relationship

The first quartile ($Q_1$) represents the 25th percentile, the median ($Q_2$) represents the 50th percentile, and the third quartile ($Q_3$) represents the 75th percentile.

Answer:

75
