About LinkBackshi there, do you how many samples were taken?
This is kind of important for constructing a conficence interval.
A bus company official wanted to estimate the mean time for the trip between two cities.A random sample of such trips gave a mean of 152 minutes and a standard deviation of 12 minutes.Construct a 98% confidence interval for the population mean time.
show me the solution how to do this question...thx
Your class notes and/or textbook will certainly explain what you have to do and have clear examples on how to do it. Have you read them? Where are you stuck?Originally Posted by SLJSWW
