Binomial distribution is negatively skewed when
- p = -1/2
- p = 0
- p > 1/2
- p < 1/2
- p = 1/3
The mean, median and mode for binomial distribution will
be equal when
- p > 0:5
- p = 0:5
- None of these
- p = 1
- p < 0:5
The mean of binomial distribution is
- (npq)^1/2
- np
- (np)^1/2
- (nq)^1/2
- npq
A random variable X has binomial distribution with n = 10
and p = 0.3 then variance of X is
- 10
- 2.1
- 12
- None
- 21
In a binomial probability distribution it is impossible to nd
- P(X < 0)
- P(X > 0)
- P(X = 0)
- P(0=< X =< n)
The probability of success changes from trial to trial in
- Hypergeometric Distribution
- Binomial Distribution
- Geometric Distribution
- Sampling Distribution
If in a binomial distribution n = 1 then E(X) is
- q
- 1
- None
- p
- 0
Each trial in Binomial distribution has
- Four Outcome
- Three Outcome
- Two Outcome
- One Outcome
In binomial distribution n=6 and p=0.9, then the value of
P(X=7) is
- Less than zero
- More than zero
- One
- Zero
In which distribution successive trials are without
replacement
- Binomial Distribution
- Poisson Distribution
- Hypergeometric Distribution
- Geometric Distribution
Successive trials in binomial distribution are
- Dependent
- None
- Mutually Exclusive
- Independent
- Equally Likely
Binomial distribution is symmetrical when
- p > q
- np > npq
- p = q
- p < q
A fair coin is tossed four times, the probability of getting four
heads is
- 1/16
- 1/2
- 1/4
- 0
- 1
Which of the following is not the property of binomial
distribution
- has two outcomes

- Trials are independent
Binomial distribution has parameters
- Three
- One
- Four
- Two
The variance of binomial distribution is always
- Less than mean
- None of these
- Greater than mean
- Equal to standard deviation
- Equal to mean
