Consider the women's 100-yd dash (and the subsequent 100-m dash) in the Olympics since records have been kept. Determine the best way to combine all data and depict the data. Choose the correct answer below. O A. A line graph would be the best way to show all of the data over time, but some measurements would have to be converted to display the 100-yd and 100-m on the same graph. OB. A scatterplot would show the relationship between the 100-yd dash and the 100-m dash. O C. A stem and leaf plot would be the best way to show all of the data grouped by race times. O D. A histogram would show all of the data by comparing each year. The units of distance would not matter.

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.
QUESTION 10 An outlier is an individual value that: OA. deviates from the pattern. B. extends the pattern. O C. determines the strength of the relationship. O D. outlines the general form of the data.
Which graph has a line that represents the best fit for the recorded data?
