You have collected the following data on all of your classmates' happiness levels. One student in particular (student 8) appears... unusually... happy, and you wonder if their happiness score significantly differs from the entire rest of the class. Following the four hypothesis testing steps, complete a one-sample z test and write a results. section. Table 1 Student Happiness Scores Student Student 1 Student 2 Student 3 Student 4 Student 5 Student 6 Student 7 Student 8 Step 1: Write a null hypothesis. Happiness Level 4 6 7 25 2 4 7 9 Step 2: Write an alternative hypothesis (one tailed or two tailed, it doesn't matter what you choose). Step 3: What is your critical value? Step 4: What is the mean of the dataset? Step 5: What is the standard deviation of the dataset? Step 6: What is the z score for student 8's happiness score (hint: in the z score formula, you will need to find n to calculate standard error; n is the number of data points in your sample. Consider who is the population and who is the sample for this practice problem) Step 7: Make a decision. Are your findings significant? Step 8: Write a results section (Hint: Remember, this is not a creative writing course, use the 4-sentence template from the lecture).
