Image transcription textA research group conducted an extensive survey of 2968 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?" 1514 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 2.4% of the population percentage? (Hint: Use p & 0.51 as a preliminary estimate. Round your answer up to

the nearest whole number.)

Three-circle, red-on-white is one distinctive pattern painted on ceramic vessels of the Anasazi period found at an archaeological site. Suppose that at one excavation, a sample of 181 potsherds indicated that 66 were of the three-circle, red-on-white pattern.

LO USE SALT Im

(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. (Enter your answer in the form: lower limit to upper limit. Include the word "to." Round your numerical values to three

decimal places.)... Show more
