Suppose a 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. These dataare presented in the following table along with each person's age group. Complete parts a. through c. below.1 Click the icon to view the data table.a. Using a = 0.025, perform a chi-square test to determine if age group and social networking site used are independent of one another.Identify the null and alternative hypotheses for a chi-square test of independence based on the information in the table. Choose the correct answer below.O A. Ho: Age group and social networking site are independent of one another.H: Age group and social networking site are not independent of one another.O B. Ho: Age group and social networking site are independent of one another.H,: The age group affects the social networking site.OC. Ho: Age group and social networking site are not independent of one another.H,: Age group and social networking site are independent of one another.O D. Ho: Age group and social networking site are independent of one another.H1: The social networking site used affects the age group.Calculate the chi-square test statistic. If necessary, combine age groups.(Round to two decimal places as needed.)Find the chi-square critical value, xa(Round to two decimal places as needed.)Determine the result of the test. Choose the correct answer below.O A. Reject Ho. The test statistic falls into the rejection region.O B. Reject Ho. The test statistic does not fall into the rejection region.OC. Fail to reject Ho. The test statistic falls into the rejection region.O D. Fail to reject Ho. The test statistic does not fall into the rejection region.

a. It is needed to test, whether age group and social networking site used are independent of one…

b. What conclusions can be made based on these results? There is (1) - evidence to indicate that (2) c. Determine the p-value using technology and interpret its meaning. p-value = _ (Round to three decimal places as needed.) Interpret the meaning of the p-value. . The p-value is the probability of observing a (3) as extreme or more extreme than the one observed under the assumption that the (4). is true. A p-value less than the significance level a means that the (5). (6) - enough that the (7). should be rejected.
