TV Viewing. The A. C. Nielsen Company collects data on the TV viewing habits of Americans and publishes the information in Nielsen Report on Television. Suppose that you want to use a paired sample to decide whether the mean viewing times of married men and married women differ.arrow_forwardConsider 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_forward
- Please answer number 4, a-e. Thanksarrow_forwardPlease answer number 3 from a-e. Thanks!arrow_forwardAssume you want to know whether the prices of meatballs change during the christmas holiday season. You therefore go to 14 meat-stores before the holiday to check the prices of one kilo of meatballs. In the middle of the holidays, you walk around to the same 14 meat-stores and check the prices again. The results of your research is seen in the table in the picture below. Make a hypothesis test, where you test whether the prices have changed between the two surveys. Use ? = 0.05arrow_forward
