The dimensions of the Head Probe are based on what percentile of a 5-year-old?

  1. 95th percentile

  2. 75th percentile

  3. 50th percentile

  4. 25th percentile

The correct answer is: 95th percentile

The dimensions of the Head Probe are based on the 95th percentile of a 5-year-old. This means that the dimensions of the probe are designed to fit the average size head of a 5-year-old. Option B, 75th percentile, is not the correct answer as it refers to a head size that is smaller than the average. Option C, 50th percentile, is also not the correct answer as it refers to a head size that is smaller than the average. Option D, 25th percentile, is the incorrect answer as it refers to a head size that is much smaller than the average. It is important to use the 95th percentile as the benchmark for the Head Probe's dimensions to ensure that it fits the majority of 5-year-olds.
