Question

Suppose the rate of leukemia was greater than expected in a given community.  Researchers wondered if living near a fertilizer plant increased the chance for getting this form of cancer.  Answer the questions below about hypothesis testing.

Apply to scenario described above: Suppose you conducted a case control study and the odds ratio is 6.18 with a p value of 0.043. What does this mean for your H0?

Answer 1

Given that odds ratio = 6.18

p value = 0.043

We know that when odds ratio is greater than 1, result is statistically significant. In this case, odds ratio = 6.18 > 1, this means that the result is significant.

Similarly, if calculated p value is less than 0.05, we have statistically significant result and we reject the null hypothesis Ho.

In this case, p value = 0.043 < 0.05, so result is significant.

Therefore, we will reject Ho based on odds ratio and p value
