Textbook Question

Chapter 8.3, Problem 14P

Archaeology: Pottery Santa Fe black-on-white is a type of pottery commonly found at archaeological excavations in Bandelier National Monument. At one excavation site a sample of 592 potsherds was found, of which 360 were identified as Santa Fe black-on-white (Bandelier Archaeological Excavation Project: Summer 1990 Excavations at Burnt Mesa Pueblo and Casa del Rito, edited by Kohler and Root, Washington State University).

(a) Let p represent the population proportion of Santa Fe black-on-white potsherds at the excavation site. Find a point estimate for p.

(b) Find a 95% confidence interval for p. Give a brief statement of the meaning of the confidence interval.

(c) Check Requirements Do you think the conditions np> 5 and nq > 5 are satisfied in this problem? Why would this be important?
