By coincidence, Cassie's Paint Supplies sold equal quantities of two paint colors yesterday:
yellow and blue. All yellow paint comes in 15-liter containers while blue paint is sold in
containers of 9 liter. What is the smallest amount of each paint color the store must have
sold?

Arandom sample of 15 observations is used to estimate the population mean. the sample mean and the standard deviation are calculated as 172 and 63, respectively. assume that the population is normally distributed. a. with 99 confidence, what is the margin of error for the estimation of the population mean? b. construct the 99% confidence interval for the population mean. c. construct the 95% confidence interval for the population mean. d. construct the 83% confidence interval for the population mean. hint: you need to use excel function =t.inv.2t to find the value of t for the interval calculation.
