The sample mean score was 106.4. Scores on this test are known to have a standard deviation of σ=10. It is desired to construct a 90% confidence interval for the mean IQ score of students at this college. Next Post Suppose a geyser has a mean time between eruptions of 63 minutes. If the interval of time between the eruptions is normally distributed with standard deviation 25 minutes, answer the following questions.
