True or False:
13. A classical probability measure is a probability assessment
that is based on relative frequency.
14. The probability of an event is the product of the probabilities
of the sample space outcomes that correspond to the event.
15. If events A and B are independent, then P(A|B) is always equal to P(A).
16. Events that have no sample space outcomes in common and,
therefore cannot occur simultaneously are referred to as mutually
independent events.
17. The binomial experiment consists of n independent, identical
trials, each of which results in either success or failure and the
probability of success changes from trial to trial.
18. The standard deviation of a binomial distribution is
np(1-p).
19. In a binomial distribution the random variable X is discrete.
20. The standard deviation and mean are the same for the standard
normal distribution.
21. In a statistical study, the random variable X = 1, if the house is colonial and X = 0 if the house is not colonial, then it can be stated that the random variable is continuous.
22. For a continuous distribution, P(X ≤ 10) is the same as P(X<10).
23. For a continuous distribution, the exact probability of any particular 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 the binomial distribution without continuity correction.
25. All continuous random variables are normally distributed.
