Identify, from the following, the moment used as a measure of skewness?

Which of the following is the most relevant for deriving a point estimate?

If a discrete random variable X follows uniform distribution and assumes only the values 8, 9, 11, 15, 18, 20, the value of P(|X-14| < 5) will be:

For the random variable X with probability density function f(x) = (x−3)² /5; x = 3, 4, 5, the variance of X is:

If the second and third moment about the origin are 8 and 18 and the third moment about mean is -14 , then the first moment about the origin is:

For frequency distribution presentation , which option is wrong.

If A and B are mutually exclusive, the general addition rule is:

For the production data
