Question

In a survey of 1016 ​people, 778 people said they voted in a recent presidential election. Voting records show that 74​% of eligible voters actually did vote. Given that 74​% of eligible voters actually did​ vote, (a) find the probability that among 1016 randomly selected​ voters, at least 778 actually did vote.​ (b) What do the results from part​ (a) suggest?

​(a) ​P(Xgreater than or equals778​)equals nothing ​(Round to four decimal places as​ needed.) ​

(b) What does the result from part​ (a) suggest? (MULTIPLE CHOICE)

A. Some people are being less than honest because ​P(xgreater than or equals778​) is at least​ 1%.

B. People are being honest because the probability of ​P(xgreater than or equals778​) is less than​ 5%.

C. People are being honest because the probability of ​P(xgreater than or equals778​) is at least​ 1%.

D. Some people are being less than honest because ​P(xgreater than or equals778​) is less than​ 5%.

The probability of flu symptoms for a person not receiving any treatment is 0.047. In a clinical trial of a common drug used to lower​ cholesterol, 58 of 1120 people treated experienced flu symptoms. Assuming the drug has no effect on the likelihood of flu​ symptoms, estimate the probability that at least 58 people experience flu symptoms. What do these results suggest about flu symptoms as an adverse reaction to the​ drug? ​

(a) ​P(Xgreater than or equals58​)equals nothing ​(Round to four decimal places as​ needed.) ​

(b) What does the result from part​ (a) suggest? (MULTIPLE CHOICE)

A. The drug has no effect on flu symptoms because xgreater than or equals58 is not highly unlikely.

B. The drug increases the likelihood of flu symptoms because xgreater than or equals58 is highly unlikely.

C. The drug increases the likelihood of flu symptoms because xgreater than or equals58 is not highly unlikely.

D. The drug has no effect on flu symptoms because xgreater than or equals58 is highly unlikely.
