To determine the percentage of high school football players weighing 242 pounds or more from the box plot, you would typically look for the weight value on the plot and see where it falls in relation to the quartiles.
First, identify the median weight on the box plot. The median weight is the weight that falls exactly in the middle of the data set.
Next, identify the upper quartile (Q3) of the box plot. The upper quartile is the weight that divides the top 25% of data from the bottom 75% of data.
If the weight of 242 pounds falls between the median and the upper quartile, you can estimate the percentage of high school football players weighing 242 pounds or more by calculating the percentage of players above the weight of 242 pounds.
The formula to calculate the percentage of players above 242 pounds is:
(Number of players above 242 pounds / Total number of players) x 100.
By using this formula and the information from the box plot, you can estimate the percentage of high school football players weighing 242 pounds or more.
