Question

Refer to the accompanying technology display. The probabilities in the display were obtained using the values of n equals 5n=5 and p equals 0.795p=0.795. In a clinical test of a drug, 79.579.5% of the subjects treated with 10 mg of the drug experienced headaches. In each case, assume that 55 subjects are randomly selected and treated with 10 mg of the drug. Find the probability that more than one subject experiences headaches. Is it reasonable to expect that more than one subject will experience headaches? Binomial with nequals=55 and pequals=0.7950.795 x P(Xequals=x) 0 0.00040.0004 1 0.00700.0070 2 0.05440.0544 3 0.21120.2112 4 0.40940.4094 5 0.31760.3176

Explanation / Answer

Solution:-

=> P(X=1) + P(X=2) + P(X=3) + P(X=4) + P(X=5)

= 0.0070 + 0.0544 + 0.2112 + 0.4094 + 0.3176

= 0.9996
