Hypothesis:
Mean number of recorded participants
Calculated test statistic = 13.86
Critical value = -1.751

Rejection region:
If the calculate test statistic is less than the critical value, we fail to accept the null hypothesis and reject it.
We accept the alternate hypothesis.
Since,
We fail to reject the null hypothesis and accept it. Thus, the test result are not statistically significant and and at best provide weak evidence against the null hypothesis.
