A scientist is interested in whether stretching before running 5 kilometers will improve a runner's time. The
scientist decides that an experimental study is the best method to use to answer the question. One group of
runners will run a 5-kilometer race without stretching, and a second group of runners will follow a specific
stretching routine before running the race. The finishing times will be recorded, along with the group type for
each runner
The group that raced without stretching has a mean finish time of 23.5 minutes and a standard deviation of 2.6
minutes. Write a sentence or two that summarizes any conclusions that can be made about the statistical
question, "Does stretching before running a race improve a runner's time?"
