How would I calculate this: Santa Fe black-on-white is a type of pottery commonly found at archaeological excavations at a certain monument. At one excavation site a sample of 588 potsherds was found, of which 350 were identified as Santa Fe black-on-white.
(a) Let p represent the proportion of Santa Fe black-on-white potsherds at the excavation site. Find a point estimate for p. (Round your answer to four decimal places.)
(b) Find a 95% confidence interval for p. (Round your answers to three decimal places.) lower limit/upper limit. Give a brief statement of the meaning of the confidence interval.
(c) Do you think that np> 5 and nq> 5 are satisfied for this problem? Explain why this would be an important consideration.
