An agency reports that 10.08% 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.

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 0.05, what is your conclusion? Reject Ho There is sufficient evidence to conclude that there has been an increase in union membership. Do not reject He There is insufficient evidence to conclude that there has been an increase in union membership. Do not reject Ho- There is sufficient evidence to conclude that there has been an increase in union membership. Reject H. There is insufficient evidence to conclude that there has been an increase in union membership.
