1. The U.S. Bureau of Labor Statistics reports that 11.6% of U.S. workers belong to unions. Suppose a sample of 397 U.S. workers is collected in 2014 to determine whether union efforts to organize have increased union membership. The sample results show that 51 of the workers belonged to unions.

Compute the test statistics.

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 have increased union membership. The sample results show that 41 of the workers belonged to unions.

Compute the p-value.

3. 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 have increased union membership at 0.025 level of significance. The sample results in a test statistic (z) of 1.31.

We conclude that union membership increased in 2014. (Enter 1 if the conclusion is correct. Enter 0 otherwise.)

The U.S. Bureau of Labor Statistics (BLS) wishes to estimate the fraction of individuals who belong to a labor union. They are considering two methods of sampling. For each method, explain if you think it will be subject to selection bias (Yes or No) and why, and if it will be subject to non-response bias (Yes or No) and why. Also state whether you think each method will result in too small (downward bias) or too large (upward bias) an...
