normally distributed for this example? Explain why/why not.
True or False: We can use the standard deviation obtained from the sample to estimate the population standard deviation. Select one: O True False
As we do not know the population standard deviation, which distribution should we use to determine the 95% confidence interval for the population mean time to complete the pizza order? Select one: a. t-distribution b. Z-distribution C. F-distribution d. chi-square distribution
What assumption do we need to make in order that a confidence interval can be constructed? Select one: a. Distribution is normally distributed b. The data is skewed C. No assumption is necessary d. The standard deviation is small
