Question

According to the Bureau of the Census, 18.1% of the U.S. population lives in the Northeast, 21.9% in the Midwest, 36.7% in the South, and 23.3% in the West. In a random sample of 200 recent calls to a national 800-number hotline, 39 of the calls were from the Northeast, 55 from the Midwest, 60 from the South, and 46 from the West. At the 0.05 level, can we conclude that the geographical distribution of hotline callers could be the same as the U.S. population distribution?
