write your answer in 1. Which of the following statements is TRUE about the interpretation of the values of variance and standard deviation? A. A small value of variance or standard deviation indicates that the distribution of the discrete random variable is closer about the mean. B. A large value of variance or standard deviation indicates that the distribution of the discrete random variable is closer about the mean. C.A small value of variance or standard deviation indicates that the distribution of the discrete random variable takes some distance from the mean. D. All of the above. 2. In 50 items test, Miss Santos, a mathematics teacher claimed that most of the students' scores lie closer to 35. In this situation, score of 35 is considered as, A. Variance C. Expected Value or Mean B. Standard Deviation D. Median 3. Which of the following statement describes variance of a discrete random variable? A. It is a weighted average of the possible values that the random variable can take. B. It is the product of mean and the square of the probability distribution of a discrete random variables. C. It is obtained by getting the summation of the product of the square of the difference between the value of X and the expected value times its corresponding probability D.All of the above
