In a test of hypotheses, a researcher used the level of significance a = .05. Based on a random sample, she obtained a P-value of 0.052. Which of the following is true?
A. She may conclude that H0 is true because her sample provides evidence to support it.
B. Her sample provides little to no evidence for Ha.
C. There is some evidence against H0, and a study using a larger sample size may be worthwhile.
D. The data suggest that further investigation of the hypotheses (using another sample and study) will not be significant at the a= 0.05 significance level.
