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(Nod)
hi there, do you how many samples were taken?
This is kind of important for constructing a conficence interval.
Re: Confidence interval.
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?
