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 find the sample mean x and sample standard deviation s. (Round your answers to one decimal place.) x = cm s = cm...
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?
need help to correct my mistake 8. Suppose the mean of rim diameter of 31 ceramic vessels is 15.8 cm with standard deviation is 3.3 em. The diameter ofceramic vessels is normally distributed. Compute a 90% confidence interval for the population mean μ ofrim diameters for such ceramic vessels found at the archaeological site. (6 points) 65 the mean of rim dicemete, s 15,8 .69( s between 476cm an 16,937 s-H.740
Wind Mountain is an archaeological study area located in southwestern New Mexico. Potsherds are broken pieces of prehistoric Native American clay vessels. One type of painted ceramic vessel is called Mimbres classic black-on-white. At three different sites the number of such sherds was counted in local dwelling excavations. Shall we reject or not reject the claim that there is no difference in population mean Mimbres classic black-on-white sherd counts for the three sites? Test given Given that P-Value > 0.1,...
