Unknown cultural affiliations and loss of identity at high elevations. These are words used to propose the
Question:
Let p1 be the population proportion of unidentified archaeological artifacts at the elevation zone 70007500 ft in the given archaeological area. Let p2 be the population proportion of unidentified archaeological artifacts at the elevation zone 50005500 ft in the given archaeological area.
(a) Find a 99% confidence interval for p1 - p2.
(b) Explain the meaning of the confidence interval in part (a) in the context of this problem. Does the confidence interval contain all positive numbers? all negative numbers? both positive and negative numbers? What does this tell you (at the 99% confidence level) about the population proportion of unidentified artifacts at high elevations (70007500 ft) compared with the population proportion of unidentified artifacts at lower elevations (50005500 ft)? How does this relate to the stated hypothesis?
