You may need to use the appropriate appendilx table or technology to answer this question. An agency reports that 11.2% of workers in a particular country belonged to unions. Suppose a sample of 400 workers is collected to determine whether union efforts to organize have increased union membership. (a) Formulate the hypotheses that can be used to determine whether union membership has increased. O Ho: P< 0.112 Hp2 0.112 o "o: P2 0.112 H:p< 0.112 Ho:p > 0.112 H:ps 0.112 Ho:p- 0.112 Hp+ 0.112 Ho:ps0.112 Hp> 0.112 (b) If the sample results show that 52 of the workers belonged to unions, what is the p-value for your hypothesis test? Find the value of the test statistic. (Round your answer to two decimal places.) Find the p-value. (Round your answer to four decimal places.) p-value - (c) At a - 0.05, what is your conclusion? O Do not reject Ho. There is sufficient evidence to conclude that there has been an Increase in union membership.
