Shards of clay vessels were put together to reconstruct rim diameters of original ceramic vessels found at the Wind Mountain archaeological site. A random sample of 15 ceramic vessels gave a mean of 15.8 and a standard deviation of 3.5cm. What test would you use to construct a 95% confidence interval for this problem?

Three-circle, red-on-white is one distinctive pattern painted on ceramic vessels of the Anasazi period found at the Wind Mountain archaeological site. At one excavation, a sample of 164 potsherds indicated that 76 were of the three-circle, red-on-white pattern. How many ceramic potsherds must be found and identified if we are to be 95% confident that the sample proportion p̂ of such potsherds is within 5.0% of the population proportion of three-circle, red-on-white patterns found at this excavation site? (Round your...
