Standard Deviation given Optimistic and Pessimistic Time Solution

Follow our step by step solution on how to calculate Standard Deviation given Optimistic and Pessimistic Time?

FIRST Step Consider the formula

σ = \frac{T Pessimistic - T optimistic}{6}

Next Step Substitute values of Variables

∴

σ = \frac{10d - 9d}{6}

Next Step Convert Units

∴

σ = \frac{864000s - 777600s}{6}

Next Step Prepare to Evaluate

∴

σ = \frac{864000 - 777600}{6}

Next Step Evaluate

∴

σ = 14400s

Next Step Convert to Output's Unit

∴

σ = 0.166666666666667d

LAST Step Rounding Answer

∴

σ = 0.1667d
