Question: Suppose the following ``two-way table'' describes, for a sample of 1,000 people, the approximate average noise level while awake, versus the number who passed a statistics test.
small noise | moderate noise | lots of noise | |
passed | 70 | 300 | 220 |
didn't pass | 30 | 200 | 180 |
Does the data suggest, at significance level 0.05, that noise level while awake, and passing statistics tests, are dependent? Use a χ2 test. Be sure to include a ``yes'' or ``no'' final answer.
