Question

You  randomly sample 50 theaters in the United States.  You ask those theaters how much they charge for a large

popcorn, and you get a sample mean of $6.  Then, you create a confidence interval using this data with the lower limit at $4.50 and the upper limit at $7.50.  Explain why a confidence interval would or would not be appropriate? If you only had a sample of 10 theaters instead of 50, would a confidence interval still be appropriate?  Why or why not?
