Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.

Using the Mann-Whitney $U\,$ value of 14 that was calculated in part (b) (where $n_1 = 7$ and $n_2 = 9$ ), determine whether Liam's data are significant at $\leq 0.05\,$ for a non-directional (two-tailed) hypothesis. Use the table of critical values below to justify your answer.

Table of critical values for Mann-Whitney $U\,$ at $\leq 0.05$ (two-tailed)

$n_1$	$n_2 = 7$	$n_2 = 8$	$n_2 = 9$
7	8	10	12
8	10	13	15
9	12	15	17

Note: For significance to be shown, the calculated value of $U\,$ must be equal to or less than the critical value.
