The 5 fourth-grade classes at brown elementary raised a total of $2,462 to purchase playground equipment. write and solve an equation that shows one way to estimate the amount raised by each class.

$2462 ÷ 5 = $492.40

Step-by-step explanation: Do division

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."
