Consider an Experiment in Which a Pharmaceutical Company Is Testing

Consider an experiment in which a pharmaceutical company is testing a new drug that they hope will lower cholesterol levels. They administer three treatments: A dose of the drug, a dose of a placebo, and a control group that receives neither drug nor placebo. after 24 hours they then measured the cholesterol levels and compared the values to baseline levels measured prior to treatment. The table below shows the results of the experiment.
​​ $\begin{array}{|l|l|l|}\hline \text { Treatment } & \text { Chol. lower } & \begin{array}{l}\text { Chol. increased } \\\text { or the same }\end{array} \\\hline \text { Drug } & 64 & 36 \\\hline \text { Placebo } & 51 & 49 \\\hline \text { Control } & 48 & 52 \\\hline\end{array}$
-Assuming a null hypothesis of no relationship between diet and weight gain, which of the following values is closest to the expected count of individuals in the placebo group that showed lower cholesterol levels?

A) 46
B) 49
C) 51
D) 54
