Question

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)
