Suppose the marketing research firm 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, 369 social network users were asked which site they primarily visited. At the 0.05 level of significance, can we conclude that the two variables are related? These data are presented in the following table along with each person’s age group: Age (Years) Facebook Twitter LinkedIn 10-17 7 22 0 18-34 44 54 25 35-54 40 38 44 55 and older 26 38 31 a. What test should you run? b. Select the correct hypothesis statements. H0: H1: c. Compute the value of the test statistic? (Round your answer to 2 decimal places. Negative values should have a minus sign in front of them) d. Determine the p-value (Round your final answer to 4 decimal places.) e. What is your decision regarding the null hypothesis? multiple choice Fail to reject the null. Reject the null. f. Interpret the result.
