Math question. how should you interpret a decision that fails to reject the null hypothesis?
A null hypothesis is basically opposite to the hypothesis that you propose. In this case, the null hypothesis would be: The mean IQ of stats teachers is not greater than 130. If someone fails to reject the null hypoth, that is to say that they are unable to provide sufficient evidence to reject the idea that that the mean IQ of stats teachers is no greater than 130. In other, words, based on evidence provided, the null is still possible. So, the answer would be D.
