Question
and Poisson distributions are distributions. a. discrete b. continuous c. both discrete and continuous d. neither discrete nor continuous 8. Events are independent if a. event A occurs then event B cannot happen b. event A occurs then the likelihood of B is altered event A occurs then the likelihood of B is not altered event A occurs then B must occur c. d. The Poisson distribution is a. negatively skewed b. positively skewed c. symmetrical d. continuous 9. 10. Which of the following is a requirement of the binomial probability distribution? There are only two outcomes b. a. The trials are dependent. the probability of success changes from trial to trial. d. c. The probability of success is small. 11. In a normal probability distribution, the mean is always equal to the median a. b. always larger than the median always smaller than the median d. c. never equal to the mode. distribution. The normal probability distribution is a a. continuous b. discrete c. binomial d. Poisson 12. a A normal probability distribution is completely described by a. mean only b. variance only c. mean and standard deviation d. standard deviation only 13.Explanation / Answer
Solution:
7. The binomial and Possion distribution are discrete distribution
8. Events are indepedent if, event A occurs, then the likelyhood of B is not altered
9. The Possion distributuion is Symmetrical
10. There are only 2 outcomes
11. Always equal to the median
12.Continuous
13.Mean and Standard Deviation
