The probability of flu symptoms for a person not receiving any treatment is 0.02

Question

The probability of flu symptoms for a person not receiving any treatment is 0.028. In a clinical trial of a common drug used to lower cholesterol. 30 of 986 people treated experienced flu symptoms. Assuming the drug has no effect on the likelihood of flu symptoms, estimate the probability that at least 30 people experience flu symptoms. What do these results suggest about flu symptoms as an adverse reaction to the drug? P(X Greaterthanorequalto 30) (Round to four decimal places as needed.) What does the result from part (a) suggest? The drug increases the likelihood of flu symptoms because x Greaterthanorequalto 30 is highly unlikely. The drug increases the likelihood of flu symptoms because x Greaterthanorequalto 30 is not highly unlikely. The drug has no effect on flu symptoms because x Greaterthanorequalto 30 is highly unlikely. The drug has no effect on flu symptoms because x Greaterthanorequalto 30 is not highly unlikely.

Explanation / Answer

miu = 30 / 986 * 986 = 30

SD = seqtr ( 30 / 986 * 986 * ( 1 - 30/986 ) = 5.39

P( z > 30 - 30 / 5.39 )

P( z> 0 ) 0.50000

the grus has no effect on flue sympton because x > 30 is not highly unlikelyu
