For a Binomial distribution mean is always
Correct Answer: D
Question 3 Explanation:
Mean = np
Variance = npq, where q=(1-p)
Logically we are multiplying some number q =1-p to mean to get variance and q belongs to [ 0,1]. so if we multiply a value less than 1 to np to get npq then
np>=npq.
Variance = npq, where q=(1-p)
Logically we are multiplying some number q =1-p to mean to get variance and q belongs to [ 0,1]. so if we multiply a value less than 1 to np to get npq then
np>=npq.
greater than variance
less than variance
equal to variance
greater than or equal to variance
