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...
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 176 potsherds indicated that 62 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?

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 165 potsherds indicated that 70 were of the three-circle, red-on-white pattern. (a) 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.) (b) Compute a 95% confidence interval for the population proportion p of all ceramic...
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 70 were of the three-circle, red-on-white pattern. (a) 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.)

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 19 potsherds indicated that were of the three-circle, red-on-white pattern (a) Find a point estimate p for the proportion of all ceramic potsherds at this site that are of the three-cinder, red-on-white pattern. (Round your answer to four decimal places (b) Compute a 95% confidence interval for the population proportion p of all ceramic potsherds with this...
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?
From public records, individuals were identified as having been charged with drunken driving not less than 6 months or more than 12 months from the starting date of the study. Two random samples from this group were studied. In the first sample of 30 individuals, the respondents were asked in a face-to-face interview if they had been charged with drunken driving in the last 12 months. Of these 30 people interviewed face to face, 17 answered the question accurately. The...
Another type of painted ceramic vessel is called three-circle red-on-white ( Mimbres Mogollon Archaeology). At four different sites in an archaeological region, the number of such sherds was counted in local dwelling excavations.
