Considering the given confidence interval, the value of the sample proportion is of 0.55.

What is a confidence interval?

A confidence interval is given by the sample proportion plus/minus the margin of error.

Hence, the sample proportion is the mean of the two bounds, as the interval is symmetric.

In this problem, the bounds are 0.52 and 0.58, hence:

p = (0.52 + 0.58)/2 = 0.55.
