You may need to use the appropriate appendix table or technology to answer this question. An agency reports that 11.7% of workers in a particular country belonged to unions. Suppose a sample of 300 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. H0: p = 0.117 Ha: p ≠ 0.117 H0: p ≥ 0.117 Ha: p < 0.117      H0: p ≤ 0.117 Ha: p > 0.117 H0: p < 0.117 Ha: p ≥ 0.117 H0: p > 0.117 Ha: p ≤ 0.117 (b) If the sample results show that 42 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 =
