5-steps

of Solving

Hypothesis Tests

Step 1

State the hypotheses and identify the claim

Step 2

Find the critical value(s)

Step 3

Compute the test value

Step 4

Make the decision to reject or fail to reject the null hypothesis 

Step 5

Summarize the results 

*Note: The critical value is the 1- the percent (as a decimal) you want to be confident (yes just like confidence intervals) and is given in the problem, but in practice you will have to decide for yourself*
