(02.01 MC) A statistician wants to determine the relationship between typing speed, in words per minute, and the time, in minutes, it takes to type one page of a specific book. Twenty-five trials are completed and the correlation coefficient between typing speed and time is determined to be -0.622. Therefore, slower typing speed was related to greater time. How is the correlation affected if the units for time are changed from minutes to seconds?

Select one:
a. The correlation and time measurement would change proportionally to one another.
b. The correlation would stay the same because the change in units for time would have no effect on it.
c. The correlation would increase because changing the units for time would result in an increase in time values.
d. It is impossible to determine the amount of change experienced by the correlation.
e. The correlation would decrease because only the units for one of the variables changed.
