Answer:
1 is the answer
Step-by-step explanation:
Given that the U.S. Bureau of Labor Statistics reports that 11.3% of U.S. workers belong to unions.

(Right tailed test for testing of a sample proportion with population proportion)
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.
Test statistic Z = 1.31
p value for this right tailed test would be 0.095
This p value is greater than 0.025
Hence at 2.5% significance level the conclusion is correct
