Final answer:
Yes, you can use the regression line to predict the number of steps for a student who is 7 feet tall. The regression line represents the relationship between height and number of steps.
Step-by-step explanation:
Yes, you can use the regression line to predict the number of steps for a student who is 7 feet tall. The regression line is a line of best fit that represents the relationship between two variables, in this case, height and number of steps. By using the regression equation, you can plug in the height value of 7 feet and calculate the predicted number of steps.
Regression equation: y = mx + b
where y is the predicted number of steps, x is the height, m is the slope of the regression line, and b is the y-intercept. To find the predicted number of steps, you need to substitute 7 feet for x in the regression equation and calculate the value of y.
