1. If a Wilcoxon test shows that t = 3 with an
associated probability of 0.02, this means:

(a) Assuming the hypothesis to be true,
a t-value of 3 would occur 2% of the time through sampling variation

(b) We are 98% certain that our results are
statistically significant

(c) Given our data, we expect to find a
t-value of 3 occurring 2% of the time through chance

(d) If the hypothesis is not true, then
a t-value of 3 would occur 2% of the time through sampling variation

2. A t-value of 3 has been converted into a
z-score of _3.2. This
means:

(a) The calculations are
