Answer:
18 Houseboats
Step-by-step explanation:
Given the set of numbers
12 18 23 26 29
Minimum = 12
First Quartile, Q₁ = 18
Median, Q₂ = 23
Third Quartile, Q₃ = 26
Maximum = 29
The first 25% of lakes have less than or equal to 18 houseboats.
Therefore, the 5-Number Summary suggests that about 75% of lakes in Minessotta have more than 18 Houseboats.
