professor of geography

Navajo Culture: Traditional Hogans S. C. Jett is a professor of geography at the University of California, Davis. He and a colleague, V. E. Spencer, are experts on modern Navajo culture and geography. The following information is taken from their book Navajo Architecture: Forms, History, Distributions (University of Arizona Press). On the Navajo Reservation, a random sample of 210 permanent dwellings in the Fort Defiance region showed that 65 were traditional Navajo hogans. In the Indian Wells region, a random sample of 152 permanent dwellings showed that 18 were traditional hogans. Let p1be the population proportion of all traditional hogans in the Fort Defiance region, and let p2be the population proportion of all traditional hogans in the Indian Wells region.

(a) Check Requirements Can a normal distribution be used to approximate the  width=distribution? Explain.

(b) Find a 99% confidence interval for p1- p2.

(c) Interpretation Examine the confidence interval and comment on its meaning. Does it include numbers that are all positive? all negative? mixed? What if it is hypothesized that Navajo who follow the traditional culture of their people tend to occupy hogans? Comment on the confidence interval for p1- p2 in this context.
