Leroy, a starting player for a major college basketball team, made only 27.5% of his free throws last season. During the summer he worked on developing a softer shot in the hope of improving his free-throw accuracy. In the first eight games of this season, Leroy made 29 free throws in 40 attempts. Let p be his probability of making each free throw that he shoots this season. (a) State the null hypothesis H. that Leroy's free-throw probability has remained...

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 Frequency Blue 16 Green 8 Yellow 6 Red 3 Do these data provide evidence of a color...
