ANSWER:

Answer

Step 1 of 2

(a)

Patients arriving at a hospital emergency department present a variety of symptoms and complaints.

The following data were collected during one weekend night shift

We are asked to calculate the numerical summaries of these data. What practical interpretation can you give to these summaries?

Step to create the descriptive measures in Minitab:

  1. On the opening of Minitab, you will get session handler and worksheet like Excel worksheet.
  2. Enter the data into the worksheet (in this case symptoms and complaints).
  3. After entering the data go to a menu called Stat in menu panel and under that select Basic Statistics option.
  4. In the drop down menu of Basic Statistics option, select Display Descriptive Statistics.
  5. Select the variable symptoms and complaints and click ok.
  6. After clicking you will get the summary of mean, median etc.

Hence from the numerical summary, we can see that there are  patients on an average in each group.

The standard deviation is relatively large.
