Write a statement that correctly interprets the confidence interval. Choose the correct answer below. A. One has 90​% confidence
poizon [28]

Answer:

B. <em>There is a 90​% chance that the true value of the population proportion will fall between the lower bound and the upper bound. </em>

Step-by-step explanation:

A. <em>One has 90​% confidence that the sample proportion is equal to the population proportion. </em>

Confidence interval gives an interval estimate, not an equality

B. <em>There is a 90​% chance that the true value of the population proportion will fall between the lower bound and the upper bound. </em>

<em>Ture. </em>

<em>C.</em><em> One has 90​% confidence that the interval from the lower bound to the upper bound actually does contain the true value of the population proportion. </em>

Also true but <em>One has 90​% confidence is not good interpretation. </em>

<em>D</em><em>. 90​% of sample proportions will fall between the lower bound and the upper bound.</em>

<em>Lower bound and upper bound is given to estimate population proportion. </em>
