I do understand the Type $\text {I}$ error and Type $\text {II}$ error. I also do understand that
$\text{level of significance} = \text {P(Type I error)}$. However, how do I explain it to a person (having no statistics background) in very simple language. E.g. I need to make someone understand the meaning of following result:
"At the 5% level of significance, the Anderson - Darling test suggests that the loss data follows a Normal distribution"
I am bit confused as to how to make someone understand this without making things too confusing for the client.
Also, if possible, will like to know about degrees of freedom too.
