Priya conducted an observational study investigating whether there is an association between university student status (undergraduate or postgraduate) and their preferred study space (silent study zone or group work zone). She analyzed her data using a Chi-Square test of association (df=1df = 1df=1).
Priya formulated a two-tailed (non-directional) hypothesis and chose a significance level of p≤0.05p \le 0.05p≤0.05. Her calculated Chi-Square value was χ2=3.94\chi^2 = 3.94χ2=3.94.
Using the table of critical values below, determine whether there is a significant association between student status and study space preference.
| Significance level (ppp) for a two-tailed test | 0.10 | 0.05 | 0.01 |
|---|---|---|---|
| Critical value (df=1df = 1df=1) | 2.71 | 3.84 | 6.63 |
