Question 209

A psychologist conducted a study to assess the effectiveness of a new mindfulness app in reducing the number of cravings in individuals trying to quit smoking over a one-week period.

Group 1 (Experimental): Used the mindfulness app ( $N_1 = 6$ )
Group 2 (Control): Used a basic tracking app ( $N_2 = 6$ )

The calculated value of $U\,$ was found to be 5.

Table 1: Critical Values of $U\,$ for a One-Tailed Test at $\le 0.05$

$N_1$	$N_2 = 5$	$N_2 = 6$	$N_2 = 7$
5	4	5	6
6	5	7	8
7	6	8	11

Using the information provided in Table 1, explain whether the mindfulness app was significantly effective in reducing cravings.
