The probability of flu symptoms for a person not receiving any treatment is 0.056. In a clinical trial of a common drug used to lower cholesterol, 49 of 807 people treated experienced flu symptoms. Assuming the drug has no effect on the likelihood of flu symptoms, estimate the probability that at least 49 people experience flu symptoms. What do these results suggest about flu symptoms as an adverse reaction to the drug? (2) P(X 2 49) =(Round to four decimal places as needed.)
Use a normal approximation to find the probability of the indicated number of voters. In this case, assume that 159 eligible voters aged 18-24 are randomly selected. Suppose a previous study showed that among eligible voters aged 18-24, 22% of them voted. Probability that fewer than 40 voted The probability that fewer than 40 of 159 eligible voters voted is. (Round to four decimal places as needed.)
