Question

The probability of flu symptoms for a person not receiving any treatment is 0.053. In a clinical trial of a common drug used to lower​ cholesterol, 63 of 1125 people treated experienced flu symptoms. Assuming the drug has no effect on the likelihood of flu​ symptoms, estimate the probability that at least 63 people experience flu symptoms. What do these results suggest about flu symptoms as an adverse reaction to the​ drug? a. P(Xgreater than or equals63​)equals b. What does the result from part​ (a) suggest? A. The drug increases the likelihood of flu symptoms because xgreater than or equals63 is highly unlikely. B. The drug increases the likelihood of flu symptoms because xgreater than or equals63 is not highly unlikely. C. The drug has no effect on flu symptoms because  xgreater than or equals63 is highly unlikely. D. The drug has no effect on flu symptoms because xgreater than or equals63 is not highly unlikely.

The drug has no effect on flu symptoms because is not highly unlikely.
