Chicago and Atlanta are cities with two of the busiest airports in the United States.
Unfortunately, both of these cities have frequent thunderstorms and other weather
problems that lead to flight delays. Henry flies frequently to both cities and suspects
that Chicago has a higher proportion of delayed flights. In two independent, random
samples he finds that Chicago has 37 out 119 flights were delayed, while Atlanta has
only 25 delayed flights out of 127 sampled flights. Is there statistically significant
evidence that the proportion of delayed flights from Chicago is higher than the
proportion of delayed flights from Atlanta? Use a = 0.05.
