举一反三
- The function f(x) that defines the probability distribution of a continuous random variable X is a:
- The probability mass between two standard deviations around the mean for a normal distribution is ________.（ ） A: 66% B: 90% C: 75% D: 95%
- The probability density function for a uniform distribution ranging between 2 and 6 is A: 4 B: undefined C: any positive value D: 0.25
- In a continuous probability distribution, the random variable: A: is limited to certain values. B: may be any value within a certain range. C: may have a probability greater than 1.00. D: is discrete.
- A description of how the probabilities are distributed over the<br/>values the random variable can assume is called a probability<br/>distribution. ( <br/>)
