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 59.7 seconds. Assuming that sigma =10.1 seconds, construct and interpret a 90% confidence interval estimate of the population mean of all students.
What is the 90% 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.

16 students were randomly selected from a large group of
students taking a certain calculus test. The mean score for the
students in the sample was 86 and the standard deviation was 1.3.
Assume that the scores are normally distributed. Construct a 98%
confidence interval for the mean score, μ, of all students taking
the test. Round your answer to two decimal places.
