1. Shards of clay vessels were put together to reconstruct rim diameters of the original ceramic vessels found at the Wind Mountain archaeological site. A random sample of ceramic vessels gave the following rim diameters (in cm): 15.9 13.4 22.1 12.7 13.1 19.6 11.7 13.5 17.7 18.1 Compute an 80% confidence interval for the population mean µ of rim diameters for such ceramic vessels found at the Wind Mountain archaeological site. a. Write the formula you will be using in the space below (1 point) b. Identify all corresponding values associated with your symbols in the space below (2 points) c. Plug in your values and show your work in the space below (3 points) d. Sketch your distribution, identify your endpoints and label them, shade the area in which your population mean would fall (1.5 points) e. Interpret your results within the context of the problem (1.5 points)

Question #1 Three-circle, red-on-white is one distinctive pattern painted on ceramic vessels of the Anasazi period found at an archaeological site. At one excavation, a sample of 163 potsherds indicated that 74 were of the three-circle, red-on-white pattern. Find a point estimate p̂ for the proportion of all ceramic potsherds at this site that are of the three-circle, red-on-white pattern. (Round your answer to four decimal places.) Compute a 95% confidence interval for the population proportion p of all ceramic...
