Navajo Reservation, a random sample of 214 permanent dwellings in the Fort Defiance region showed that 70 were traditional Navajo hogans. In the Indian Wells region m sample of 149 permanent dwellings showed that 23 were traditional hogans. Let p, be the population proportion of all traditional hogans in the Fort Defiance region, a pulation proportion of all traditional hogans in the Indian Wells region. LO USE SALT (a) Find a 90% confidence interval for p, - P,. (Use 3 decimal places.) lower limit upper limit (b) 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 Na follow the traditional culture of their people tend to occupy hogans? Comment on the confidence interval for p, - p, in this context. O Because the interval contains only positive numbers, we can say that there is a higher proportion of hogans in the Fort Defiance region. O Because the interval contains both positive and negative numbers, we can not say that there is a higher proportion of hogans in the Fort Defiance region. O We can not make any conclusions using this confidence interval
