1.The U.S. Bureau of Labor Statistics reports that 11.3% of U.S. workers belong to unions. Suppose a sample of 400 U.S. workers is collected in 2014 to determine whether union efforts to organize haveincreasedunion membership at 0.025level of significance.The sample results in a test statistic (z) of 2.1.

We conclude thatunion membership increased in 2014.(Enter 1if the conclusionis correct. Enter 0 otherwise.)

2.The U.S. Bureau of Labor Statistics reports that 10% of U.S. workers belong to unions. Suppose a sample of 400 U.S. workers is collected in 2014 to determine whether union efforts to organize haveincreasedunion membership.The sample results show that 46of the workers belonged to unions.
