The data we obtained by surveying 120 individual students in both “LFS” and “non-LFS” faculties showed that: 73% and 60% of the LFS students and non-LFS students consume healthy snack foods. From the statistical analysis of our data, we fail to reject the null hypotheses for both of our z-test and Chi-square test.

From the Z-test of our data, we fail to reject the null hypothesis that the proportion of LFS students who eat healthy foods are the same as that of non-LFS students. There is no significant difference between the the proportion of LFS students and non-LFS students who eat healthy foods (Figures 1 and 2).

Figure 1. This pie graph shows that 73% of the LFS students consumed healthy food whereas 27% of the LFS students consumed unhealthy food.

Figure 2. This pie graph shows that 60% of the non-LFS students consumed healthier food and 40% consumed less healthy foods.

From our Chi-squared test of our data, we fail to reject the hypothesis that there is no association between faculty and the consumption levels of healthy food. Faculty and the level of consumption of healthy food is independent (Figure 3).

Figure 3. This bar chart shows that there is no significant difference between the the proportion of LFS students and non-LFS students who eat healthy foods.
