Question

In general terms, describe the steps involved in testing a hypothesis using statistical methods.

Answer #1

A hypothesis test is a procedure for testing a claim about property of population.

**7 Step Process of Statistical Hypothesis
Testing:**

**Step 1: State the Null Hypothesis**

H0 :μ1 = μ2 =⋯ = μk

**Step 2: State the Alternative Hypothesis**

H_{A}: treatment level means not all equal

**Step 3: Set α**

If we look at what can happen in a hypothesis test, we can construct the following contingency table:

**Step 4: Collect Data**

Remember the importance of recognizing whether data is collected through an experimental design or observational.

**Step 5: Calculate a test statistic**

**Step 6: Construct Acceptance / Rejection
regions**

**Step 7: Based on steps 5 and 6, draw a conclusion about
H _{0}**

Discuss how the concept of statistical independence underlies
statistical hypothesis testing in general. Based on statistical
analysis, are we justified in asserting that two variables are
statistically dependent? Why or why not? Explain why researchers
typically focus on statistical independence rather than statistical
dependence.
