Question

Quizplus · Accepted Answer

The rejection of the null hypothesis that hospital admission is independent of season indicates that there is a relationship between them. Therefore, option C, "Hospital admissions vary by season," is the best conclusion to draw. The test does not provide information about which season has the most or least admissions, so options A and B are not valid conclusions. Option D is also not valid, as the test shows that there is a significant difference among seasons.
