Suppose the marketing research firm com-Score would like to examine if the social networking site that a person primarily uses is influenced by his or her age. In a randomly drawn sample, 355 social network users were asked which site they primarily visited. These data are presented in the following table along with each person’s age group:

a. Using α = 0.05, perform a chisquare test to determine if the age group of a social network user and the site he or she primarily visits are independent.

b. What conclusions can be made based on these results?

c. Determine the p_value using Excel and interpret its meaning.

d. Verify your results using p_value.
