Randomly selected students participated in an experiment to test their ability to determine when one minute​ (or sixty​ seconds) has passed. Forty students yielded a sample mean of 62.4 seconds. Assuming that σ=8.5 seconds, construct and interpret a 99​% confidence interval estimate of the population mean of all students.

What is the 99​% confidence interval for the population mean μ​?

Time perception. Randomly selected college students participated in an experiment that tested their ability to determine the course of 1 minute (or 60 seconds). Forty students produced a sample mean of 58.3 seconds. Assuming that the standard deviation is 9.5 seconds, use a significance level of 0.05 to test the assertion that the population mean is less than 60 seconds.
