Question

Which option identifies the correct conclusion from the experiment in the following scenario?

Dr. Clark and Dr. Smith are conducting an experiment to test the effect on mice of a certain drug for depression.
They give 250 of the mice the drug and the other 250 receive a tablet with none of the drug. Of the mice given
the drug, 1 mouse became active and lost weight on the drug, 229 mice remained healthy and behaved normally,
10 mice had mild side effects like lethargy and increased heart rate, and 10 mice died during the research. Of the
250 mice in the untreated group, 240 mice remained healthy and behaved normally, and 10 mice died during the
research. The researchers want to publish that the drug caused weight loss in the one mouse.
The mouse's weight loss may or may not have been caused by the drug. The scientists' observations may not be
repeatable
The mouse's weight loss is an observation that should be published, like when Fleming found one Petri dish that was
different from the others.
The mouse's weight loss is clearly caused by the drug. The scientists have conducted a good randomized controlled trial
The mouse's weight loss shows the experiment is clearly flawed and the scientists are ignoring data that show the drug is
dangerous

Answer 1

250 mice in the untreated group, 240 mice remained healthy and behaved normally, and 10 mice died during the

research. The researchers want to publish that the drug caused weight loss in the one mouse.

The mouse's weight loss may or may not have been caused by the drug. The scientists' observations may not be

repeatable
