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
