what is the p-value
a p value <0.05 is what
the chance of a Type 1 error (false positive) is <5%….
can p values be specific and in a range
what value can the p value never be
how many decimal places does a p value have
what is a type 1 error
what is a type 2 error
what is alpha
what is beta
is it difficult to get a significant p value
what is the mean
what is the SD
if asked to summarise a study what do we talk about
if the null hypothesis is rejected what is true
if the null hypothesis is rejected what is false
if the null hypothesis is accepted what is true
if the null hypothesis is accepted what is false

When is t distribution used
What do the difference between 1 and 2 tailed depend on
