Steps in the p-value approach to hypothesis testing in correct order

1. Specify the null and alternative hypotheses 2. Calculate the value of the test statistic and its p-value 3.State the conclusion and interpret results

The equivalent methods to solve a hypothesis test are the

1. critical value approach 2. p-value approach

In inferential statistics, we use ______ information to make inferences about an unknown _________ parameter

Sample ; population

When testing "u", the p-value is the probability of obtaining a sample mean at least as extreme as the one derived from a given sample, assuming that the _______ hypothesis is true

null

When performing a hypothesis test on "u", the p-value is defined as the

observed probability of making a Type I error
