Question
**Educational Content: Reconstructing Rim Diameters of Ceramic Vessels**

Sherds of clay vessels were assembled to reconstruct the rim diameters of the original ceramic vessels at the Wind Mountain archaeological site. A random sample of ceramic vessels provided 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 four decimal places.)

- \(x = \) cm
- \(s = \) cm

(b) Compute a 98% confidence interval for the population mean \(\mu\) 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
