Q1.
Null Hypothesis: The consumption of alcohol and other drugs was the same in social events
in last year and this year.
Alternative Hypothesis: The consumption of alcohol and drugs was greater in this year’s
social event than last year’s social event.
Null Hypothesis: The amount of SDs consumed in the last peer based celebration and the
school leaver party were the same.
Alternative Hypothesis: The amount of SDs consumed in the two parties were different.
Q2.
What kind of sampling method did they use, and what are the advantages and disadvantages
of recruiting participants in this way?
A self-report methodology was used and respondents were asked question in the survey both
before and after the event.
Some of the disadvantages of this kind of self-report survey are:
1. Answers in self-reported survey may be exaggerated.

2. The researcher may arrange questions he thinks will be suitable for his research
Q3.
What are the demographic characteristics of the people in the sample? Explain by referring to
the descriptive statistics reported in the paper.
The survey was completed in two parts.
In the pre celebration sample there were 541 people out of which 56 % were female and 44 %
were male. 91 % of the teenagers were 17 years old and the remaining 9 % were 18 years old.
Out of the total students sampled 87 % of the students were enrolled in a private school.
In the post celebration sample there were 405 people out of which 50 % were female and 50
% were male. 94 % of the teenagers were 17 years old and the remaining 6 % were 18 years
old or older. Out of the total students sampled 92 % of the students were enrolled in a private
school.

What inferential statistics were used to analyse data in this study, and why?
A series of Wilcoxon signed rank tests were performed to compare AOD use between the
contexts of the last event and an average day at the leavers’ celebrations.
