- Consider a question one could have come across in college, career, or personal life. Describe and apply the five steps below. Five Step Process for Hypothesis Testing: Step 1: State the hypothesis to be tested. Step 2: Specify the decision rule. Step 3: Collect data and calculate necessary statistics to test the hypothesis. Step 4: Make a decision. Step 5: Take action based on the decision. An example: Step 1: State the hypothesis to be tested. Ho: I will go to class today, Ha: I will not go to class today. Step 2: Specify the decision rule. If there is a "high" probability of rain, I will not go to class. If P(rain) ≤0.70, I will go to class (Fail to Reject Ho). Step 3: Collect data and calculate necessary statistics to test the hypothesis. Watch the Weather Channel, check local news, check iphone app to collect data. Statistics for today: Weather Channel: P(rain)=0.50 Local News: P(rain)=0.40 iphone app: P(rain)=0.65 Step 4: Make a decision. All of the statistics…arrow_forwardWhat I Can Do Directions: Cite five (5) situations in your community where you can apply hypothesis testing. Then, just choose one situation and: 1. create a problem statement; 2. formulate the null and alternative hypothesis; 3. select the level of significance and sketch the rejection region; and 4. state the possible Type I and Type II errors.arrow_forwardDetermine the first step of hypothesis testing, and explain the procedure and logic of this step. Choose the correct answer below. A. The first step is to determine the level of significance at which to conduct the hypothesis test. The conventional levels of significance used are 5% and 1%, which are described as the 0.05 significance level and the 0.01 significance level, respectively. When a sample score is so extreme that researchers reject the null hypothesis, the result is said to be statistically significant. B. The first step is to restate the question as a research hypothesis and a null hypothesis about the populations. Since researchers are interested in the results in terms of the population, it is useful to restate the research question in terms of populations. The research hypothesis represents the research question being asked. C. The first step is to determine the characteristics of the comparison distribution. The overall logic of hypothesis…arrow_forward
