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...

To decide on the number of service counters needed for stores to be built in the future, a supermarket chain wanted to obtain information on the length of time (in minutes) required to service customers. To find the distribution of customer service times, a sample of 60 customers' service times was recorded and are shown here. 0.5 1.2 5.2 1.2 0.4 3.7 0.3 0.2 3.1 1.6 0.6 2.3 1.8 0.4 2.8 1.2 1.0 1.3 1.0 0.8 1.9 1.0 0.5 1.0...
