举一反三
- 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
- The point estimation is to determine an interval bounded by 2 values such that the probability that the parameter value is within the interval is known.( )
- 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.
