Birds use color to select and avoid certain
types of food. The authors of a particular article studied the
pecking behavior of 1-day-old bobwhites. In an area painted white,
they inserted four pins with different colored heads. The color of
the pin chosen on the bird's first peck was noted for each of 33
bobwhites, resulting in the accompanying table. Color First Peck

Questions 15-16: In an article, the authors compare the use of humor in TV ads in the United States and in the United Kingdom. A random sample of 100 TV ads in the United States reveals that 45 use humor, while a random sample of 120 TV ads in the United Kingdom reveals that 35 use humor. Let pi and p2 represent the true proportion of ads using humor in the United States and in the United Kingdom respectively. If...
