Hypothesis test
The following hypothesis were tested in this study
1. Null hypothesis (H0): The proportion of international students accessing part time jobs is
equal to 20%.
Alternative hypothesis (H0): The proportion of international students accessing part time
jobs is less than to 20%.
2. Null hypothesis (H0): The proportion of male international students accessing part time
jobs is equal to the proportion of female international students accessing part time jobs.
Alternative hypothesis (H0): The proportion of male international students accessing part
time jobs is significantly different from the proportion of female international students
accessing part time jobs.
Results
Descriptive Statistics
We first present the descriptive statistics of the study. We can see from table 1 below that
majority of the participants (70%, n = 70) in the study were male students while the female
students were represented by 30% (n = 30).

Valid
Male 70 70.0 70.0 70.0
Female 30 30.0 30.0 100.0
Total 100 100.0 100.0

Respondents were asked why they feel it is difficult to get part time jobs. Majority (41%, n = 41)
stated frustrations from the host country as the major setback for them to get part time jobs,
language barrier was the second most contributing factor (25%, n = 25), inflexible working hours
and lack of work experience contributed to 20% (n = 20) and 14% (n = 14) respectively.
Figure 1: Why it is difficult to get part time jobs
In terms of job preference, majority (49%, n = 49) would like to have seasonal jobs, followed by
18% (n = 18) who would prefer internship. 17% (n = 17) the participants would prefer on-
campus while 16% (n = 16) would prefer off-campus.

Hypothesis tests
Hypothesis 1:
The first hypothesis that this study sought to test was whether the proportion of international
students who have access to part time job is equal to or less than 20%. The tested hypothesis is
given below;
Null hypothesis (H0): The proportion of international students accessing part time jobs is equal to
20%.
Alternative hypothesis (H0): The proportion of international students accessing part time jobs is
less than to 20%.
Using a one-sample proportion t-test the data was analyzed at 5% level of significance and the
results are given below;

As can be seen, the proportion of international students accessing part time jobs was 16% (p =
0.16). The analysis of the one-sample t-test showed the p-value to be 0.000 (a value less than 5%
level of significance), we therefore reject the null hypothesis and conclude that the proportion of
international students accessing part time jobs is less than to 20%. This proportion is actually
significant less than the hypothetical proportion of 20%.
Hypothesis 2:
The second hypothesis that this study sought to test was whether the proportion of male
international students who have access to part time job is equal to that of the female international
students. The tested hypothesis is given below;
Null hypothesis (H0): The proportion of male international students accessing part time jobs is
equal to the proportion of female international students accessing part time jobs.
Alternative hypothesis (H0): The proportion of male international students accessing part time
jobs is significantly different from the proportion of female international students accessing part
time jobs.
The results are given in table 4 and table 5 below;

As can be seen from the above tables, the proportion of male international students with access
to part time jobs is 16% while the proportion of female international students with access to part
time jobs is 17%. The p-value was found to be 0.906 (a value greater than 5% level of
significance), this leads to non-rejection of the null hypothesis and so we conclude that there is
no significant evidence to say that the proportion of male international students accessing part
time jobs is different from the proportion of female international students accessing part time
jobs.
