Question 1c In order to create the criteria for the committee we have to look at what they want from the project. Most businesses and organisations are in business to make a profit‚ however the committee has different aims and objectives compared to a normal business or organisation.

Premium Probability theory Variance Normal distribution
A population of measurements is approximately normally distributed with mean of 25 and a variance of 9. Find the probability that a measurement selected at random will be between 19 and 31. Solution: The values 19 and 31 must be transformed into the corresponding z values and then the area between the two z values found. Using the transformation formula from X to z (where µ = 25 and σ √9 = 3)‚ we have z19 = (19 – 25) / 3 = -2 and z31 = (31 - 25) / 3 = +2 From the area between z =±2 is 2(0
