The horizontal axis in the sampling distribution of ModifyingAbove p with caret represents all possible sample proportions from a simple random sample of size n. 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?

Complete Question

The horizontal axis in the sampling distribution of 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?

a

 90% of  all possible sample proportions

b

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

Step-by-step 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

the answer is 15% decrease
