Answer to Question 1

B
All measures of central tendency are equal in the normal curve.

D
The null hypothesis states that chance (and not the independent variable) is responsible for the results. If the probability of this is less than alpha, it is very unlikely that chance is responsible for the results, and the null hypothesis should be rejected.
