Sherds of clay vessels were put together to reconstruct rim diameters of the original ceramic vessels at the Wind Mountain archaeological site†. A random sample of ceramic vessels gave the following rim diameters (in centimeters).
15.9 | 13.4 | 22.1 | 12.7 | 13.1 | 19.6 | 11.7 | 13.5 | 17.7 | 18.1 |
(a) Use a calculator with mean and sample standard deviation keys to find the sample mean x and sample standard deviation s. (Round your answers to one decimal place.)
x = | cm |
s = | cm |
(b) Compute a 99% confidence interval for the population mean
μ of rim diameters for such ceramic vessels found at the
Wind Mountain archaeological site. (Round your answers to one
decimal place.)
lower limit | cm |
upper limit | cm |
