Be careful and read the directions!! These are not easy. You might need to review your notes. Which statements are true for a one-tailed test (assume we're in the right-hand tail)? (Select all that apply.) C] alpha is the area of the tail to the right of the critical value. C] Effect size is large if and only if the p-value is less than alpha C] alpha is the probability of getting a result as extreme or more extreme than the critical value by chance if the null is true. Reject the null if and only if the obtained value is more extreme than the critical value. Reject the null if and only if the p-value is less than the alpha-value. C] p is the area of the tail to the right of the obtained value. The obtained value is more extreme than (i.e. greater than) the critical value if and only if the p-value is less than alpha-value. C] p is the probability of getting a result as extreme or more extreme than the obtained value by chance if the null is true. 3
