Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.

MENSA is an international organization requiring a high lQ for membership. It was founded in 1946 by Roland Berrill and Dr. Lancelot Ware as a nonpolitical society of bright people representing different points of view. To qualify for membership, one needs to have an IQ in the top 2% on some approved intelligence tests. One such test is the Stanford-Binet Intelligence Scales, which assumes that IQ scores are normally distributed with a mean of 100 and a standard deviation of 16. а. Find the proportion of people in the general population with IQs between 90 and 110. b. What is the lowest IQ score in the Stanford-Binet Intelligence Scales that would qualify you for MENSA membership? c. Leonor, a very diligent student, has an IQ score of 150. What proportion of the general population have IQ scores above Leonor's IQ score?
