ree randomly selected households are surveyed. The numbers of people in the households are 3, 5, and 10. Assume that samples of cen=2 are randomly selected with replacement from the population of 3, 5, and 10. Listed below are the nine different samples. omplete parts (a) through (c). 3,3 3,5 3,10 5,3 5,5 5,10 10,3 10,5 10,10 D . Find the median of each of the nine samples, then summarize the sampling distribution of the medians in the format of a table epresenting the probability distribution of the distinct median values. Sample Median Probability (Type integers or fractions. Use ascending order of the sample medians.) b. Compare the population median to the mean of the sample medians. Choose the correct answer below. O A. The population median is not equal to the mean of the sample medians (it is also not half or double the mean of the sample medians). B. The population median is equal to half of the mean of the sample medians. O C. The population median is equal to double the mean…
Question 23 This method of sampling requires selecting a random starting point, then selecting every nth item.
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 160potsherds indicated that 70 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 answer up to the nearest whole number.)

Question 23 Read and solve the problem; choose the best answer from the choices provided. At a college there are 120 freshmen, 90 sophomores, 110 juniors, and 80 seniors. A school administrator selects a simple random sample of 12 of the freshmen, a simple random sample of 9 of the sophomores, a simple random sample of 11 of the juniors, and a simple random sample of 8 of the seniors. She then interviews all the students selected. Your answer: O Systematic random sampling o Convenience sampling Stratified sampling Cluster sampling
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 166 potsherds indicated that 80 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 6.5% of the population proportion of three-circle, red-on-white patterns found at this excavation site? (Round your answer up to the nearest whole number.) potsherds
