I am writing to inquire about normality test given in nortest package. I
have a random data set consisting of 300 samples. I am curious about which
normality test in R would give me precise measurement, whether data sample
is following normal distribution. As p value in each test is different in

Next time include the package name where these functions come from AND
code that creates an example data situation and you will increase your
probability of getting a more prompt and complete reply.

What is the distribution of the p-value when the null hypothesis is true?
This is an important question that unfortunately tends to get glossed over or
left out completely in many courses due to the amount of information that needs
to be packed into them.
