Question

What three things must you know about distribution to find the probability of sums?

Short answer

We must know: mean, standard deviation and sample size of the distribution.

Step-by-step solution

Given Information

Three things are known about the distribution.

Explanation

To find the probability of sums of a distribution the three things must be known is:

$-mean\left({\mu }_x\right)$

- standard deviation $\left({\sigma }_x\right)$

- sample size $\left(n\right)$.
