Question

The probability is approximately?Should the pilot take any action to correct for an overloaded aircraft

Answer 1

Remember that

z =(x - μ)/σ

we have

μ=176.2 lb

σ=38.7 lb

x=165

substitute given values

z=(165-176.2)/38.7

Z=-0.2894

using the z-scores tables

P(x>165)=0.11386+0.50

P(x>165)=0.6139

therefore

The answer is option B
