Consider a random variable X that denotes a random delivery time anywhere between 9am and 10am. X would reasonably be A continuous uniform random variable A random variable is said to be continuous if it Is measured over an interval; can have decimal values Which of the following sample spaces would satisfy the definition of a continuous random variable? X= [0,500] The probability that a continuous random variable equals any of its values is Zero Which of the following is an example of a continuous random variable? Normal One characteristic of a well-defined probability density function of a continuous random variable X is that the area under the curve, f(x), over all values of x is Equal to one The function used to find the area under the f(x) of a continuous random variable X up to any value x is called The cumulative distribution function or CDF It is meaningful to compute the probability that a continuous random variable Is between two numbers; is greater than or equal to a number; is less than or equal to a number Which of the following statements about the variance of a continuous random variable are true?
