Question

Refer to the accompanying technology display The probabilities were obtained by entering the values of n = 5 and p = 0.751. In a clinical test of a drug, 75.1% of the subjects treated with 10 mg of the drug experienced headaches. In each case, assume that 5 subjects are randomly selected and treated with 10 mg of the drug. Find the probability that at least four of the subjects experience headaches. Is it unusual to have fewer than four subjects experience headaches? EEB Click on the icon to view the technology display The probability that at least four of the subjects experience headaches is (Round to four decimal places as needed.) Binomial with n 5 and p 0.751 Is it unusual to have fewer than four subjects experience headaches? 0.0010 0.0144 0.0871 0.2626 0.3960 0.2389 O A. Yes, because the probability that fewer than four subjects will experience headaches is unlikely O B. No, because the probability that fewer than four subjects will experience headaches is not unlikely ° C. Yes, because the probability that fewer than four subjects will experience headaches is not unlikely O D. No, because the probability that fewer than four subjects will experience headaches is unlikely The Chi-Square distribution is used to test if two variables are from populations that are independent of each other Choose one of True or False for the above statement True O False The chi-square distribution is used to find a confidence interval for one population variance or standard deviation Choose one of True or False for the above statement O True O False
