Interval. A researcher wants to estimate the mean cholesterol level of people in his city. A random sample of 21 people yields an average cholesterol level of 219, with a margin of error of t12. Assume the researcher used a confidence level of 90%. O A. The researcher can be 90% confident that the mean cholesterol level for people in his city is between 207 and 231. O B. 90% of the people sampled have cholesterol levels between 207 and 231. OC. About 9 out of 10 people in the researcher's city have cholesterol levels between 207 and 231. O D. We are 90% confident that 90% of people in the city have a cholesterol level between 207 and 231. O E. If we took many random samples of people in the city, about 9 out of 10 of them could produce a confidence interval of (207, 231).
