Question

the following is a scatter plot of the heights and weights of the students in mr. baldwin’s pe class. heights and weights (scatter plot with height in inches (55, 57.5, 60, 62.5, 65, 67.5, 70, 72.5, 75, 77.5, 80) and weight in pounds (110, 119, 128, 137, 146, 155, 164, 173, 182, 191, 200) axes, and a line of best fit). given the line of best fit, estimate the height of a student who weighs 146 pounds. a. about 67.5 inches b. about 65 inches c. about 72 inches d. about 72.5 inches

Explanation:

Step1: Locate weight=146 on x - axis

Find the value 146 on the horizontal (weight) axis of the scatter plot.

Step2: Find corresponding height on line of best fit

From the point where weight is 146 pounds, move vertically until intersecting the line of best fit, then horizontally to the height (y - axis). Observing the grid, at weight = 146 pounds, the line of best fit corresponds to a height of about 67.5 inches.

Answer:

a. About 67.5 inches
