## Optimistic Time when Standard Deviation is Known Solution

STEP 0: Pre-Calculation Summary
Formula Used
optimistic_time = -(6*Standard Deviation-Pessimistic time)
t0 = -(6*σ-tp)
This formula uses 2 Variables
Variables Used
Standard Deviation- The Standard Deviation is a measure of how spread out numbers are.
Pessimistic time - Pessimistic time is the longest time that activity could take if everything is wrong. (Measured in Day)
STEP 1: Convert Input(s) to Base Unit
Standard Deviation: 40.83 --> No Conversion Required
Pessimistic time: 365 Day --> 31536000 Second (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
t0 = -(6*σ-tp) --> -(6*40.83-31536000)
Evaluating ... ...
t0 = 31535755.02
STEP 3: Convert Result to Output's Unit
31535755.02 Second -->364.997164583333 Day (Check conversion here)
FINAL ANSWER
364.997164583333 Day <-- Optimistic time
(Calculation completed in 00.016 seconds)
