Problem 14AYU
Determine the point estimate of the population proportion, the margin of error for each confidence interval, and the number of individuals in the sample with the specified characteristic, x, for the sample size provided.
Lower bound: 0.853, upper bound: 0.871, n = 10,732
ANSWER:
Answer :
Step 1:
Here we have to determine the point estimate of the population proportion.
Let the lower bound be
. = 0.853
Let the upper bound be
.= 0.871
The formula for point estimate of the population proportion is
=
=
= 0.862
Therefore the point estimate of the population proportion is = 0.862.
