Ответ:
Independent variable = new running shoe
Dependent variable = mean time
Step-by-step explanation:
Remember, that every statistical research method employs the use of variables (properties) of things which can change in value.
Therefore, matching the variable to proposed hypothesis test could be rendered as:
"To determine whether there is a statistically significant impact of wearing the new running shoe on the mean time to run 100 meters by sprinters."
