Answer

Explanation:

Step1: Calculate the proportion

The proportion of boats from Connecticut in the first 10 boats is $\frac{5}{10}=\frac{1}{2}$.

Step2: Use the proportion to predict

Multiply the proportion by the number of new - coming boats. So for 12 boats, the expected number is $\frac{1}{2}\times12 = 6$.
