Explanation:

Step1: Recall IQR formula

The inter - quartile range (IQR) is given by $IQR = Q_3 - Q_1$, where $Q_1$ is the first quartile and $Q_3$ is the third quartile.

Step2: Find IQR for Resort A

From the box - plot of Resort A, $Q_1 = 225$ and $Q_3=300$. Then $IQR_A=300 - 225=75$.

Step3: Find IQR for Resort B

From the box - plot of Resort B, $Q_1 = 200$ and $Q_3 = 275$. Then $IQR_B=275 - 200 = 75$.

Answer:

The inter - quartile range for ski Resort A is 75 inches.
The inter - quartile range for ski Resort B is 75 inches.
