a 1-year period. The average me o = $258. confidence interval for the mean claim payment. Three-circle, red-on-white is one distinctive pattern painted on ceramic vessels of the Anasazi period found at an archaeological site. At o excavation, a sample of 161 potsherds indicated that 70 were of the %D three-circle, red-on-white pattern. a) (a) Find a point estimate o for the proportion of all ceramie potsherds at this site that are of the three-circle, red-on-white pattern. (Round your answer to four decimal places.) b) (b) Compute a 95% confidence interval for the population proportion p of all ceramic potsherds with this distinctive pattern found at the site.
