1. Statistical significance is very often mentioned in research reports.

a. When asked what it means, a student replies that "results that are statistically significant tell us that they cannot easily be explained by chance variation alone if the hypothesis tested was true." Do you think that this statement is essentially correct? Explain your answer.

b. When asked to explain the meaning of "the P-value was 0.03,0.03," a student says, "It means there is only probability 0.03 that the null hypothesis is true." Is this an essentially correct explanation? Explain your answer.
