Learn by Doing – Interpreting Non-significant Results
Suppose that only 40% of the U.S. public supported the general direction of the previous U.S. administration’s policies. To gauge whether the nationwide proportion, p, of support for the current administration is higher than 40%, a major polling organization conducts a random poll to test the hypotheses:

The results are reported to be not statistically significant, with a p-value of 0.214.
Decide whether each of the following statements is a valid conclusion or an invalid conclusion, based on the study:
