WebSpecifically, the four steps involved in using the P-value approach to conducting any hypothesis test are: Specify the null and alternative hypotheses. Using the sample data and assuming the null hypothesis is true, calculate the value of the test statistic. Hypothesis Testing Calculator = x ¯ = = Level of Significance: α = Solve Example 1 • Example 2 The first step in hypothesis testing is to calculate the test statistic. The formula for the test statistic depends on whether the population standard deviation (σ) is known or unknown.
