question 65

Multiple Choice

Even if the research hypothesis is true, an experiment may not produce significant results because:

• B)the sample that happens to be selected from the population being studied may not be extreme enough to provide a clear case for rejecting the null hypothesis
• C)the original population is very extreme with regard to its mean and standard deviation, leading the researcher to prove the null hypothesis
• D)just as there is a probability of rejecting the null hypothesis, there is always a chance that it must be accepted
