Question

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 showed a P(rain) of 0.65 or less, so Fail to Reject Ho. I will go to class. Step 5: Take action based on the decision. I went to class and it's a good thing I did because we had a pop quiz! (picture attached)
