# Suppose you took random samples from three distinct age groups. Through a survey, you determined how many respondents from each age group preferred to get news from T.V., newspapers, the Internet, or another source (respondents could select only one mode). What type of test would be appropriate to determine if there is sufficient statistical evidence to claim that the proportions of each age group preferring the different modes of obtaining news are not the same? Select from tests of independence, homogeneity, and goodness-of-fit.Since we are interested in proportions, the test for homogeneity is appropriate.Since we are determining if the current distribution fits the previous distribution of responses, the goodness-of-fit test is appropriate. Since we can claim all the variables are independent, the test of independence is appropriate.

Step 1

Given distinct age groups which came from three distinct populations and here we are testing to see if the proportions of each age group preferring different modes of obtaining news are not the same.
