Recent research indicates that the effectiveness of antidepressant medication is directly related to the severity of the depression (Khan, Brodhead, Kolts & Brown, 2005). Based on pretreatment depression scores, patients were divided into four groups based on their level of depression. After receiving the antidepressant medication, depression scores were measured again and the amount of improvement was recorded for each patient. The following data are similar to the results of the study. Low Moderate High Moderate Moderately Severe Severe 1.2...

please explain
3.3) [8 pts] A sample of 29 randomly selected automobile owners were asked to keep a record of the kilometers they travel. The random sample showed an average of 28,350 kilometers and a standard deviation of 5,237 kilometers. Assuming the underlying population is normally distributed, test the hypothesis that automobiles are driven on average more than 28,000 kilometers per year at the 10% level.
