Explanation:

Step1: Recall quartile concept

In a five - number summary (Min, Q1, Median, Q3, Max), Q1 represents the 25th percentile, Q3 represents the 75th percentile.

Step2: Analyze the question

We want to find the value such that about 75% of lakes have more than that number of house - boats. This is equivalent to finding the 25th percentile value.

The first quartile (Q1) is the 25th percentile. Given Q1 = 18.

Answer:

B. 18
