Question

Aflatoxins are toxic compounds secreted by fungus found most often in damaged crops.
Kenya experienced an outbreak of aflatoxicosis in 2004 that resulted in several hundred cases of liver failure, including 125 deaths.
The Kenyan Ministry of Health suspected that improper maize (corn) storage conditions were at least in part responsible for the outbreak.
A random sample of 27 patients with aflatoxicosis and 43 healthy controls were asked whether they stored their maize in the house or in a dedicated granary.
Prolonged storage in the house exposes crops to levels of humidity that foster fungal growth.
The study found that 22 of the patients and 23 of the controls had stored maize in the house.
Choose carefully a valid statistical method to compare the effectiveness of both storage methods against aflatoxicosis.
Do your results support the ministry's hypothesis?

Step 1:
STATE: Does the data support the notion that storing maize at the house was (at least in part ) responsible for the outbreak of aflatoxicosis?
FORMULATE: Choose carefully a valid statistical method to compare the effectiveness of both storage methods against aflatoxicosis.

a) A significance test. b) A large sample confidence interval. c) A plus-four confidence interval. d) None of the above.

Explanation / Answer

Answer to the question)

In this case we have two groups , and we need to know if the two groups have different rates. In this case we would like to test whether the difference in the two group rates is significant or not . That is the reason why a Significance test can help answer the Research Question.

Thus the correct answer choice is A
