You are told that a random sample of 150 people from Iowa has been given cholesterol tests, and 60 of these people had levels over the “safe” count of 200. Construct a 95% confidence interval for the appropriate
population parameter of people in Iowa with cholesterol levels over
200. Hint: Create a summary table of counts, prepare a well formated

(perhaps including your name and subject). Report your final interval explaining the steps that you used to reach the result. Interpret the results of the interval in context with a full and complete sentence. use excel spreadsheet |
