Final answer:
The healthiest body mass index (BMI) range is not between 15 and 18.
Step-by-step explanation:
The statement 'The healthiest body mass index (BMI) range is between 15 and 18' is False.
The Body Mass Index (BMI) is calculated by dividing a person's weight in kilograms by the square of their height in meters. A healthy BMI range is generally considered to be between 18.5 and 24.9. A BMI below 18.5 may indicate underweight.
Therefore, a BMI range of 15 to 18 would be considered underweight, not the healthiest range.
