Question

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 179 potsherds indicated that 60 were of the three-circle, red-on-white pattern.

(b) Compute a 95% confidence interval for the population proportion p of all ceramic potsherds with this distinctive pattern found at the site. (Round your answers to three decimal places.)

Answer 1

Answer :-

Given data,

Three circle, red-on-white is one distinctive pattern painted on ciramic vessels of the Anasazi period found at an archaelogical site. At one excavation, a sample of 179 potsturds indicated that 60 were of the three - circle, re-on-white pattern.

n = 179.

x = number of succes = number of potshred of three- code red on white pattern = 60.

95% confidence interval for the population proportion P of all ceramic potshreds with this distinctive pattern found at the siteis,

upper limit = 0.266

upper limit = 0.404.
