**Steve**, Tuesday, August 5, 2014 at 5:01amfor women, 2 ft is 1.6 std below the mean

for men, 2 ft is 3.33 std below the mean.

So, look those up in your Z table to see the break points.

**Anonymous**, Sunday, March 8, 2015 at 4:12pm.For women:

Mean = 2.8

SD = 0.5

P( x < 2) =

μ = 2.8

σ = 0.5

standardize x to z = (x - μ) / σ

P(x < 2) = P( z < (2-2.8) / 0.5)

= P(z < -1.6) = 0.0548 ---- 5.48 percent of women won't be able to work on this instrument panel

(From Normal probability table)

Men:

Mean = 3.1

SD = 0.6

P( x < 2) =

μ = 3.1

σ = 0.6

standardize x to z = (x - μ) / σ

P(x < 2) = P( z < (2-3.1) / 0.6)

= P(z < -1.8333) = 0.0336 --- 3.36 percent of men won't be able to work on this instrument panel

(From Normal probability table)
