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 15 Green 8 Yellow 7 Red 3 Do these data provide
evidence of a color preference (i.e. are the colors not all the
same)? Test using α = 0.01. (Assume that the sample is
representative of all 1-day-old bobwhites.) Let p1, p2, p3, and p4
be the proportions of bobwhites whose first peck is each of the
four colors. State the appropriate null and alternative hypotheses.
H0: p1 = p2 = p3 = p4 = 0.5 Ha: H0 is not true. H0: p1 = p2 = p3 =
p4 = 0.01 Ha: H0 is not true. H0: p1 = p2 = p3 = p4 = 33 Ha: H0 is
not true. H0: p1 = p2 = p3 = p4 = 0.25 Ha: H0 is not true. H0: p1 =
p2 = p3 = p4 = 8 Ha: H0 is not true. Find the test statistic and
critical value. Round your test statistic to three decimal places
and your critical value to two decimal places.) X2 = critical value
= State the conclusion in the problem context. Reject H0. There is
convincing evidence that there is a color preference. Fail to
reject H0. There is convincing evidence that there is a color
preference. Reject H0. There is not convincing evidence that there
is a color preference. Fail to reject H0. There is not convincing
evidence that there is a color preference.
The statistical software output for this problem is:
Hence,
Hypotheses: Option D is correct.
= 9.061
Critical value = 11.34
Conclusion: Option D is correct.
