Answer:
(B) 0.057
Step-by-step explanation:
The 95% confidence interval is (0.028, 0.086). The formula for the confidence interval is μ ± e where μ is the mean and e is the margin of error.
Therefore the confidence interval is (μ - e , μ + e).
That is μ - e = 0.028 and μ + e = 0.086
To get the point estimate which is the mean, we sum the two proportions and divide it by two.
Therefore point estimate (μ) = (0.028 + 0.086) / 2 = 0.057
