Question: A developmental psychologist would like to determine whether infants display any color preferences. A stimulus consisting of four color patches (red, green, blue, and yellow) is projected onto the ceiling above a crib. Infants are placed in the crib, one at a time, and the psychologist records how much time each infant spends looking at each of the four colors. The color that receives the most attention during a 100-second test

period is identified as the preferred color for that infant. The preferred colors for a sample of 60 infants are shown in the following table: Red Green Blue Yellow 20 12 18 10

a. Do the data indicate any significant preferences among the four colors? Test at the .05 level of significance.

b. Write a sentence demonstrating how the outcome of the hypothesis test would appear in a research report.
