Hi all.

When do we use binomial PD and when do we use binomial CD when it comes to the chapter of statistical hypothesis testing?

PD gives you P(X = some value)
CD gives you P(X <= some value)

For hypothesis testing you will need to use CD.

I thought the P(X=x) for a continuous distribution e.g. a normal distribution is always 0?

Binomial is a discrete distribution, not continuous.
