Refer to the previous problem. If you were to convert all of the observations of change in running speed from cm/s into mm/s, how would this change

a. The mean?

b. The standard deviation?

c. The median?

d. The interquartile range?

e. The coefficient of variation?

f. The variance?

Data from previous problem

The spider data in Example 3.2 consist of pairs of measurements made on the same subjects. One measurement is running speed before amputation and the second is running speed after amputation. Calculate a new variable called “change in speed,” defined as the speed of each spider after amputation minus its speed before amputation.
