The probability of flu symptoms for a person not receiving any treatment is 0.051. In a clinical trial of a common drug used to lowercholesterol, 47 of 835 people treated experienced flu symptoms. Assuming the drug has no effect on the likelihood of flusymptoms, estimate the probability that at least 47 people experience flu symptoms. What do these results suggest about flu symptoms as an adverse reaction to thedrug?

(a) P(X47)= _______? (Round to four decimal places asneeded.)

(b) What does the result from part(a) suggest?

A. The drug increases the likelihood of flu symptoms because x47 is highly unlikely.

B. The drug has no effect on flu symptoms because x47 is not highly unlikely.

C. The drug increases the likelihood of flu symptoms because x47 is not highly unlikely.

D. The drug has no effect on flu symptoms becausex47 is highly unlikely.
