Consider a random variable x that follows a uniform distribution with a = 5 and b = 13. Which of the following statements about x are true? Check all that apply. Any intervals of equal length have the same probability of containing x (given that the intervals are within 5 and 13). The probability that x is between 5 and 13 is zero. x follows a left-skewed distribution. The distribution of x is symmetrical about its mean. The probability that x equals a particular value is zero. x follows a rectangular distribution. x follows a right-skewed distribution.

Properties of the uniform distribution Consider a random variable X that follows a uniform distribution with a range of 10 and a minimum value of 0. Which of the following statements about X are true? Check all that apply. - The height of X's probability density function is 1/10. - X follows a rectangular distribution. - Any intervals of equal length have the same probability of containing X (given that the intervals are within 0 and 10). - X follows a left-skewed distribution. - The distribution of X is symmetrical about its mean. - The probability that X is between 0 and 10 is 1. - The total area under X's probability density function is 1.

2. Properties of the uniform distribution Consider a random variable x that follows a uniform distribution with a = 1 and b = 3. Which of the following statements about x are true? Check all that apply. The height of x's probability density function is 1/2. x follows a right-skewed distribution. The probability that x is between 1 and 3 is 1. x follows a bell-shaped distribution. x follows a rectangular distribution. The total area under x's probability density function is 1. The probability that x equals a particular value is 1/2.
