Q4. In an effort to control the spread of the malaria virus, the World Health Organization (WHO) monitors the number of new cases each month in twelve countries in Africa, to initiate containment efforts if the number of new cases exceed 20 each month in any of the twelve countries. If a random variable is used to track the number of countries in which the number of new cases have exceeded 20 each month, how many values are possible for the random variable?

Q7. A lab specialist performs lab tests on samples in Hampton, Virginia. Depending on the type of test that is performed, the lab test can take 1, 2, 3, or 4 hours. The 1, 2, and 3 hour lab tests occur at the same rate, but the 4 hour lab test occurs at twice the rate of any of the other lab tests. Develop a probability distribution for the duration of a lab test. The probability distribution satisfies the conditions required for a discrete probability function.

Q12. A dog trainer has determined that the number of weeks to fully train a dog is either 1, 2, 3, or 4 weeks, depending on the type of dog. The dog trainer developed a probability function where f(x) = x/10 where “x” is a random variable indicating the number of weeks required to fully train a dog. Which of the following statements is accurate?

The probability function is not valid because it is not a discrete uniform probability function

The probability function is valid because it meets the conditions of a discrete uniform probability function

The probability function is not valid because the sum of the probabilities do not equal to 1

The probability function is valid because it meets the conditions of a discrete probability function
