Question

Determine the point estimate of the population​ proportion, the margin of error for the following confidence​ interval, and the number of individuals in the sample with the specified​ characteristic, x, for the sample size provided. Lower bound equals 0.345​, upper boundequals0.895​, nequals1000

Answer 1

Answer:

For this case we have the following confidence interval given:

$0.345 \leq p \leq 0.895$

And for this case we want to find the estimated proportion like this:

$\hat p= \frac{0.345 +0.895}{2}= 0.62$

And the margin of error for this case would be given by:

$ME= \frac{0.895-0.345}{2}= 0.275$

Step-by-step explanation:

For this case we have the following confidence interval given:

$0.345 \leq p \leq 0.895$

And for this case we want to find the estimated proportion like this:

$\hat p= \frac{0.345 +0.895}{2}= 0.62$

And the margin of error for this case would be given by:

$ME= \frac{0.895-0.345}{2}= 0.275$
