Question 753184: I got 15.7 for A, but am not sure how to figure out B and need some assistance please and thank you

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 verify that x=15.8cm and s=3.5cm
(b) Compute a 80% confidence interval for the population mean ? of rim diameters for such ceramic vessels found at the Wind Mountain archaeological site.
