Chapter 12, Problem 33CR
The color vision of birds plays a role in their foraging behavior: Birds use color to select and avoid certain types of food. The authors of the article “Colour Avoidance in Northern Bobwhites: Effects of Age, Sex, and Previous Experience” (Animal Behaviour [1995]: 519–526) 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.
Do the data provide evidence of a color preference? Test using α ＝ 0.01.

]14. Many animals, including humans, tend
to avoid direct eye contact and even patterns
that look like eyes. Some insects, including
moths, have evolved eye-spot patterns on
their wings to help ward off predators.
Scaife (1976) reports a study examining how
eye-spot patterns affect the behaviour of
birds. In the study, the birds were tested in a
box with two chambers and were free to
move from one chamber to another. In one
chamber, two large eye-spots were painted
on one wall. The other chamber had plain
walls. The researcher recorded the amount
of time each bird spent in the plain chamber
during a 60-minute session. Suppose the
study produced a mean of M
34.5 minutes
on the plain chamber with SS = 210 for a
sample
of n =
15 birds. (Now: If the eye spots have
no effect. then the birds should spend an
average of u = 30 minutes in each chamber.)
a. Is this sample sufficient to conclude that
the eyes pots have a significant influence on
the bird's behaviour? Ike a two-tailed test

Bottled Water. A project exploring the bottled-water phenomenon and preference of water types was conducted by researchers M. Lunsford and A. Fink in the article “Water Taste Test Data” (Journal of Statistics Education, Vol. 18, No. 1). One hundred nine subjects participated in double-blind taste tests of three different bottled water brands (Fiji, Aquafina, and Sam’s Choice) and tap water. Twelve people preferred the tapwater, 27Aquafina, 44 Fiji, and 26 Sam’s Choice. At the 5% significance level, do the data provide sufficient evidence to conclude that the four different water types are not equally likely in preference?
One game at a carnival is called “Duck Pond.” This game consists of a large number of ducks that arefloating through an oval-shaped trough. A sign claims that 20% of the ducks have a blue dot on thebottom of them, 20% have a red dot, 20% have a green dot, 20% have a yellow dot, and 20% have anorange dot. Players pay to select one duck, show the color to the game attendant, replace the duck, spinaround once, and then select a second duck. If the dot on the bottom of the second duck matches the dotthat was on the bottom of the first duck, the player wins. Otherwise, the player loses.
a) Are the events “color of the first duck” and “color of the second duck” independent? Explain.
b) You want to perform a simulation to estimate the probability of winning this game, assuming theduck colors are distributed as claimed. Describe how you could use a table of random digits tocarry out this simulation without needing to skip any digits.
c) Perform 10 trials of the simulation described in part (b)…

- A researcher wanted to study the tendency of our choices to be influenced by our environment, so she conducted an experiment. The researcher recruited 90 volunteers. She randomly assigned 30 to sit in a room with red walls, 30 to sit in a room with yellow walls, and 30 to sit in a room with orange walls. After sitting in the room doing mundane activities, she offered them all a snack of strawberries, bananas, or oranges. For each individual, she recorded which room the participant was in and which snack they chose. The data are displayed in the table. The researcher would like to know if these data provide convincing evidence that the distribution of snack choice differs for the various room colors in the population of all volunteers like these.

In the original study, men were shown women’s photographs presented on either a white or a red background. Photographs presented on red were rated significantly more attractive than the same photographs mounted on white. In a similar study, a researcher prepares a set of 30 women’s photographs, with 15 mounted on a white background and 15 mounted on red. One picture is identified as the test photograph and appears twice in the set, once on white and once on red. Each male participant looks through the entire set of photographs and rates the attractiveness of each woman on a 10-point scale.

Subiects were asked to evaluate an advertisement for bathroom fittings that contained an art image, a nonart image, or no image. The art image was Vermeer's painting Girl with a Pearl Earring, and the nonart image was a photograph of the actress Scarlett Johansson in the same pose wearing the same garments as the girl in the painting and was taken from the motion picture Girl with a Pearl Earring. Thus the art and nonart images were a match on content. College students were divided at random into three groups of 39 each, with each group assigned to one of the three types of advertisements. Students evaluated the product in the advertisement on a scale of 1 to 7, with 1 being the most unfavorable rating and 7 being the most fa vorable.
