Formulate a hypothesis statement and perform the five-step hypothesis testing procedure
What hypothesis did you use?

I'm stuck and don't know where to begin
To formulate a hypothesis statement and perform the five-step hypothesis testing procedure, you can follow these steps:
Step 1: State the Hypotheses
- Start by stating the null hypothesis (H0) and the alternative hypothesis (H1).
- The null hypothesis is the statement to be tested, assuming there is no significant effect or difference.
- The alternative hypothesis is the opposite statement, assuming there is a significant effect or difference.
Step 2: Set the Significance Level (α)
- The significance level is the probability of rejecting the null hypothesis when it is true.
- It is typically set at 0.05 or 0.01, representing a 5% or 1% chance of making a Type I error (rejecting the null hypothesis incorrectly).
Step 3: Collect the Data
- Gather the relevant data for your analysis.
- Ensure that your sample is representative of the population you want to draw conclusions about.
Step 4: Perform the Test
- Depending on the nature of your hypothesis statement and data, choose an appropriate statistical test.
- Examples include t-test, chi-square test, ANOVA, etc.
- Perform the chosen test and calculate the test statistic.
Step 5: Make a Decision and Interpret the Results
- Compare the calculated test statistic with the critical value(s) from the corresponding statistical distribution.
- If the test statistic falls within the critical region (beyond the critical value(s)), reject the null hypothesis; otherwise, fail to reject the null hypothesis.
- Interpret the results in the context of the problem and your hypothesis statement.
It's important to note that the final decision is based on statistical evidence and does not guarantee absolute truth. The conclusion should be drawn cautiously and considered in light of other factors.
