Question: Create two sets of data, at least 5 numbers each (numbers in the first set should be all different and between 1 and 20, and numbers in the second set should be also all different but between 20 and 40). Explain what the data represent. What is the best measure of center in each group and why? Which set of data has bigger variation and why?
PART I: For this part, we will divide the data set into two groups: those who have infection and those who do not. Consider only those who have an infection.1. For these subjects only, construct a stemplot for the variable “heart rate”. (We will be making this into a back-to-back stemplot later, so leave room on the left side.)2. Discuss the shape of your stemplot. Is it symmetric? Positively skewed? Negatively skewed? None of these? Are there any outliers?3. How would you describe the center and the spread of this distribution?4. Find the five-number summary.5. Construct a box plot.
