Lindvall Real Estate Virtual Tours produces videos of 12 minutes in length with a standard deviation of 3 minutes. The mean and standard deviation reported are population parameters. Suppose we select a sample of 64 videos produced by Lindvall Real Estate Virtual Tours. To what issues does one need to be alert to complete this problem? a. On what chapter is this problem based? Is there an identical example in that chapter? Report the page number(s) of that example. b. What can we say about the shape of the distribution of the sample mean time? What can we say about its dispersion? c. What is the standard error of the mean time? d. What percent of the sample means that we could possibly generate would have a sample mean greater than 12.7 minutes?
