In a large population, 3% have had a heart attack. Suppose a medical researcher randomly selects two people. Let X represent the event the first person has had a heart attack. Let Y represent the event the second person has had a heart attack. Which of the following is true about the two events? X and Y are disjoint. X and Y are independent. None of the above are true. Both (A) and (B) are true. plese show expakin how and why and all steps how to check it

Solutions

Expert Solution

Answer:

Correct Answer: Option (B) X and Y are independent

Since First person heart attack is not affected by the second person heart attack and vice-versa, so the two events are independent

Within this group, 10 suffered heart attacks; among the 200 athletically inactive adults, 26 had suffered heart attacks.                    a) Test the hypothesis that the proportion of adults who are active and sufferedheart attacks is different...
