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?
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
