- 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_forwardDirections: Follow the steps in testing the hypothesis to answer the following problems. a. Identify the given in the problem. b. State the null and alternative hypotheses. c. Determine the test statistic, then compute its value. d. Find the critical value and draw the critical region. e. Draw a conclusion A teacher believes that less than 20% of the students like Mathematics. If 13 out of the 60 randomly selected students like mathematics, is the teachers' claim valid? Use 90% confidence level.arrow_forwarda. Identify the null and alternative hypotheses for this test. Choose the correct answer below. b. Identify the test statistic for this hypothesis test. c. The P-value for this hypothesis test is d. Identify the conclusion for this hypothesis test.arrow_forward
- What 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 second step of hypothesis testing, and explain the procedure and logic of this step. Choose the correct answer below. A. The second step is to figure out the probability of getting a particular result if the research hypothesis is true. In this process, one wants to determine the probability of getting a sample score as extreme as the one found if the sample were from a population with a distribution corresponding to the research hypothesis being true. B. The second step is to determine if the test should use a directional hypothesis or a nondirectional hypothesis. Once this is determined, the correct cutoff sample scores can be obtained. C. The second step is to determine the characteristics of the comparison distribution. The overall logic of hypothesis testing involves figuring out the probability of getting a particular result if the null hypothesis is true. In this process, one wants to determine the probability of getting a sample score as…arrow_forwardPlease use the five steps in hypothesis testing. (a) Meteorology: Storms Weatherwise is a magazine published by the American Meteorological Society. One issuegives a rating system used to classify Northeaster storms that frequently hit New England and can cause muchdamage near the ocean. A severe storm has an average peak wave height of μ=16.4 ft for waves hitting the shore. Suppose that a Northeaster is in progress at the severe storm class rating. Peak wave heights are usually measured from land (using binoculars) off fixed cement piers. Suppose that a reading of 36 waves showed on average wave height of x̄=17.3 ft. Previous studies of severe storms indicate that σ=3.5 ft. . Does this information suggest that the storm is perhaps temporarily increasing above the severe rating? Use a=0.01arrow_forward
