Bold (a )What percent of sample proportions results in a 90​% confidence interval that includes the population​ proportion? Bold (b )What percent of sample proportions results in a 90​% confidence interval that does not include the population​ proportion?

Answer 1

Complete Question

The horizontal axis in the sampling distribution of
`\^p` represents all possible sample proportions from a simple random sample of size n.

a. What percent of sample proportions results in a 90​% confidence interval that includes the population​ proportion?

b. What percent of sample proportions results in a 90​% confidence interval that does not include the population​ proportion?

Answer:

a

90% of all possible sample proportions

b

(100% - 90% = 10% ) of all possible sample proportions

Explanation:

Generally given from the question that the horizontal axis of a represent all possible sample proportion then then the percent of the sample proportion that result in 90% interval that includes the population​ proportion is 90% of all possible sample proportions

Generally given from the question that the horizontal axis of a represent all possible sample proportion then the percent of the sample proportion that result in 90% interval that does not include the population​ proportion is (100% - 90% = 10% ) of all possible sample proportions
