A.One example of a difference between discrete random variables and continuous random
variables is that in a discrete distribution P(x > 2) = P(x = 3) while in a continuous distribution
P(x > 2) is treated the same as P(x = 2).
B.The probability distribution for a continuous random variable is represented by a probability
density function that defines a curve.
C.The parameters of a normal distribution are the mean and the standard deviation.
D.The standard normal distribution has a mean of 0 and a standard deviation of 1.0.
E.The higher the level of confidence, the wider the confidence interval must be.
F.The t-distribution is used to obtain the critical value in developing a confidence interval when
the population distribution is not known and the sample size is small
