True or False:

13. A classical probability measure is a probability assessmentthat is based on relative frequency.

14. The probability of an event is the product of the probabilitiesof the sample space outcomes that correspond to the event.

15. If events A and B are independent, then P(A|B) is alwaysequal to P(A).

16. Events that have no sample space outcomes in common and,therefore cannot occur simultaneously are referred to as mutuallyindependent events.
17. The binomial experiment consists of n independent, identicaltrials, each of which results in either success or failure and theprobability of success changes from trial to trial.
18. The standard deviation of a binomial distribution isnp(1-p).

19. In a binomial distribution the random variable X isdiscrete.

20. The standard deviation and mean are the same for the standardnormal distribution.

21. In a statistical study, the random variable X = 1, if thehouse is colonial and X = 0 if the house is not colonial, then itcan be stated that the random variable is continuous.

22. For a continuous distribution, P(X ? 10) is the same asP(X<10).

23. For a continuous distribution, the exact probability of anyparticular value is always zero.

24. For a binomial probability experiment, with n = 60 and p=.2, it is appropriate to use the normal approximation to thebinomial distribution without continuity correction.

25. All continuous random variables are normallydistributed.
