Question

Range rule of thumb for maximum value and minimum value of 1 girl in 10 births

Answer 1

The Range Rule of Thumb says that the range is about four times the standard deviation.

$R = 4\sigma$

Since range R = Maximum Value - Minimum Value

Max Value $= \mu+ 2\sigma$

Min Value $= \mu - 2\sigma$
