Baseball player's BMI

The MLB also offers to let you analyze their weight data. Again, both are available as regular Python lists: height_in and weight_lb. height_in is in inches and weight_lb is in pounds.

It's now possible to calculate the BMI of each baseball player. Python code to convert height_in to a numpy array with the correct units is already available in the workspace. Follow the instructions step by step and finish the game! height_in and weight_lb are available as regular lists.

  • Create a numpy array from the weight_lb list with the correct units. Multiply by 0.453592 to go from pounds to kilograms. Store the resulting numpy array as np_weight_kg.
  • Use np_height_m and np_weight_kg to calculate the BMI of each player. Use the following equation: $$ \mathrm{BMI} = \frac{\mathrm{weight (kg)}}{\mathrm{height (m)}^2}$$ Save the resulting numpy array as bmi.
  • Print out bmi.
