EQuestion Help The probability of flu symptoms for a person not receiving any treatment is 0.018. In a clinical trial of a common drug used to lower cholesterol, 17 of 821 people treated experienced flu symptoms. Assuming the drug has no effect on the likelihood of flu symptoms, estimate the probability that at least 17 people experience flu symptoms What do these results suggest about flu symptoms as an reaction to the drug? (a) PX217)(Round to four decimal places as needed.) (b) What does the result from part (a) suggest? O A. The drug increases the likelihood of flu symptoms because x2 17 is highly unlikely O B. The drug has no effect on flu symptoms because x2 17 is highly unlikely ? ?. The drug has no effect on flu symptoms because x217 is not highly unlikely O D. The drug increases the likelihood of flu symptoms because x2 17 is not highly unlikely

Explanation / Answer

This will be a binomial distribution with parameters:

n = 821, p = 0.018

Hence,

a) P(Atleast 17)

= P(X > 17)

= 1 - P(X < 16)

= 1 - binom.dist(16, 821, 0.018, True) [Excel Formula]

= 0.3137

b) Option C is correct.
