PROBABILITY STATEMENTS
- Probability of meeting a Target Date,say
36 days.
- Z (Standard normal deviate) = (36 - 31.66)/2.45
= 4.34/2.45 = 1.77
- Area from normal tables = 0.9616
- Probability of exceeding a ceiling, say
28 days
- Z (Standard normal deviate) =(28 - 31.66)/2.45
= -3.66/2.45 = - 1.49
- Area from normal tables = 0.0681
- Probability of duration lying in an interval,
say 28 to 36 days
Area from normal tables = 0.9616 - 0.0681 = 0.8935
