A research group conducted an extensive survey of 3094 wage and salaried workers on issues ranging from relationships with their bosses to household chores. The data were gathered through hour-long telephone interviews with a nationally representative sample. In response to the question, "What does success mean to you?" 1555 responded, "Personal satisfaction from doing a good job." Let p be the population proportion of all wage and salaried workers who would respond the same way to the stated question. How large a sample is needed if we wish to be 95% confident that the sample percentage of those equating success with personal satisfaction is within 1.5% of the population percentage? (Hint: Use p x 0.50 as a preliminary estimate. Round your answer up to the nearest whole number.) In USE SALT workers Need Help? Read It 1. [-/1 Points] DETAILS BBUNDERSTAT12 7.R.011.5. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER 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 173 potsherds indicated that 62 were of the three-circle, red-on-white pattern. I USE SALT a) Find a point estimate p 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 potsherds with this distinctive pattern found at the site.
