Perform a chi-sqaure

b. What conclusions can be made based on these results? There is sufcient' evidence to indicate that age group and social networking site are not independent ofone another.' c. Determine the pvalue using technology and interpret its meaning. pvalue = l].l]14' (Round to three decimal places as needed.) Interpret the meaning of the pvalue. The pvalue is the probability of observing a test statistic as extreme or more extreme than the one observed under the assumption that the nul hypothesis ' is true)! pvalue less than the signicance level a means that the test statistic' is unlikely enough that the null hypothesis should be rejected. For this test, the pvalue is less than ' u: 0.05, so reject ' the null hypothesis. ' There is suicient' evidence to indicate that age group and social networking site are not independent of one another.' Calculate the chi-square test statistic. If necessary, combine age groups. I2 = ELSE?l {Round to We decimal places as needed.) Find the chisquare critical value, 13. I: = 539' [Round to two decimal places as needed.) Determine the result of the test. Choose the correct answer below. ? :1. Reject HI}. The test statistic talls into the rejection region. "ix B. Fail to reject H0. The test statistic falls into the rejection region. {:2- C. Reject H0. The test statistic does not fall into the rejection region. a. Using 0:: [1.05. perform a chi-square test to determine ifage group and social networking site used are independent of one another. Identity.r the nqu and alternative hypotheses for a chi-square test of independence based on the information in the table. Choose the correct answer below. "'3' A. Hu: Age group and social networking site are independent of one another. H1: The age group aects the social networking site. or" B. Hu: Age group and social networking site are independent oi one another. H1: The social networking site used affects the age group. i." C. Hu: Age group and social networking site are not independent of one another. H1 : Age group and social networking site are independent oi one another. -:'__*- D.
