Standard Normal Variation Solution

Follow our step by step solution on how to calculate Standard Normal Variation?

FIRST Step Consider the formula

Z = \frac{T z - T e}{σ}

Next Step Substitute values of Variables

∴

Z = \frac{170 - 160}{0.1667d}

Next Step Convert Units

∴

Z = \frac{170 - 160}{14400.0288s}

Next Step Prepare to Evaluate

∴

Z = \frac{170 - 160}{14400.0288}

Next Step Evaluate

∴

Z = 0.000694443055558333

LAST Step Rounding Answer

∴

Z = 0.0007
