Question

Mark each of the following as true or false and justify your response in detail with examples

s. lE we reject the nall hynothesis when conducting an ANOVA we conclude that the groups have different means 6. A negative odds ratio is an indication that exposure decreases the odds of disease.

Answer 1

Answer

(5) TRUE, because the null hypothesis is ANOVA assumes that there is no difference between the group means and alternate hypothesis assumes that there is a significant difference between the group means.

So, when the null hypothesis is rejected, then we can say that there is a significant difference between the group means.

so, the given statement is true

(6) TRUE, a negative odds ratio tells us that the odds ratio for the test group or the exposure group are less than the placebo or control group, which means that the odds ratio are decreased for the exposure decreasing the odds ratio

therefore, given statement is true
