Children of three different ages—5 years, 7, years, and 9 years--were given a list of 5 different animals and asked which animal they would choose to be if they could be that animal for one day. A chi-square test for homogeneity on the data produced a test statistic of
χ2 = 13.89, which yields a P-value of 0.0847. Using a significance level of α = 0.05, which of the following is the appropriate conclusion for this test?
a) Reject H0: there is convincing evidence that the distribution of animal choices is different for at least one of the age groups. b) Accept H0: there is convincing evidence the distribution of animal choices is the same for all three age groups.
c) Reject H0: there is insufficient evidence to conclude that the distribution of animal choices is different for at least one of the age
groups.
d) Fail to reject H0: there is convincing evidence the distribution of animal choices is the same for all three age groups.
e) Fail to reject H0: there is insufficient evidence to conclude that the distribution of animal choices is different for at least one of
the age groups.

Brittany has designed four different birdcages, each with the same volume: a square pyramid, a cylinder, a cone, and a sphere. the zoo wants to use one of brittany’s designs but plans to change the volume of the cage. find the design change that would result in the birdcage with the greatest volume. a.) increase the area of the base of the square pyramid by a factor of ten. b.) increase the height of the cylinder by a factor of ten. c.) increase the radius of the cone by a factor of ten. d.) increase the radius of a sphere by a factor of ten.
