Answer 1

Considering the situation described, the confidence interval is given by:

(0.35, 0.51).

What is a confidence interval?

It is given by the estimate plus/minus the margin of error.

For this problem, we have that:

• The estimate is of 0.43.

• The margin of error is half the range of the observations, hence M = (0.48 - 0.32)/2 = 0.08.

Then, the bounds of the interval are given by:

• 0.43 - 0.08 = 0.35.

• 0.43 + 0.08 = 0.51.
