Help me please Ergonomic Question Average SD standing vertic

Help me please Ergonomic Question: Average (SD) standing vertical grip reach = 2080(80) mm for M and grip reach = 1925(73) mm for F.
Determine what percentages of M an F would be able to use the shelf if the given shelf height is 2075 mm.

Solution

Given shelf height is 2075 mm

Average vertical standing grip reach for M = 2080 mm

Average vertical standing grip reach for F = 1925 mm

For F to reach the given sheft, it would need (2075-1925) mm extra height. That is, F would require 150 mm extra from M. Now we need to check what percentage of 2075 mm is 150 mm:

= (150/2075)*100 = 7.23% of shelf height.
