It is given that $\displaystyle X$ has normal distribution with mean zero and standard deviation one. Also given that $\displaystyle P[-2 < X < 2] = 0.95$, $\displaystyle P[-2 < X < -1.5] = 0.045$. Find the probability for $\displaystyle P[0 < x < 1.5]$.

If the first quartile ($\displaystyle Q_1$) and third quartile ($\displaystyle Q_3$) of a normal distribution are 22 and 28, what is the median of the distribution?

The Mode of binomial distribution $\displaystyle B(7, \frac{1}{3})$ is

If $\displaystyle p$ is increased for a fixed $\displaystyle n$; the Binomial distribution shifts to the

The variance of a binomial distribution with parameters $\displaystyle n$ and $\displaystyle p$ is:
