ski resort visitors

what percent of the time did mountain view get at least 4,000 visitors?
%

Explanation:

Step1: Recall box plot properties

In a box plot, the box represents the interquartile range (IQR), containing the middle 50% of the data. The left edge of the box is the first quartile (\(Q_1\)), meaning 25% of the data is below \(Q_1\), and 75% is above (or at least) \(Q_1\). From the plot, the left edge of the box is at 4,000, so \(Q_1 = 4000\).

Step2: Calculate the percentage

Since 25% of the data is below 4,000, the percentage of data with at least 4,000 visitors is \(100\% - 25\% = 75\%\).

Answer:

75
