1. A possible association between smoking (yes/no) and snoring (yes/no) should be investigated.
Chi-square test of independence (Chi-square test of Association): It is a nonparametric used to test whether any association exists between the categorical variables.
In the given statement the variables smoking and snoring are categorical variables since they can be categorized into different groups (yes/no) and to test for the association between variables, the Chi-square test of independence can be used to test the association.
The appropriate test is the Chi-square test of independence (Chi-square test of Association).
2. An educating video is prepared for people about wearing a safety belt while driving. Their safety belt wearing habits were assessed before watching the video and re-assessed after a month of watching the educating video (n=17).
The Paired t-test(dependent t-test): It is used to test whether the mean difference of the paired observations is significantly different from zero. They are used in the dependent or paired data.
In the given statement safety belt wearing habits were assessed before watching the video and re-assessed after a month of watching the educating video thus the two observations are dependent on each other, thus a Paired t-test is used in this given scenario.
The appropriate test is the Paired t-test(dependent t-test)
