Answer
# Explanation:
## Step1: Calculate total number of Independents
Add the number of Independents in each opinion - category: $37 + 27+25=89$.
## Step2: Calculate relative - frequency
The relative frequency is the number of Independents divided by the total number of people surveyed. The total number of people surveyed is 298. So the relative frequency $r=\frac{89}{298}\approx0.30$.
# Answer:
$0.30$
