The standard deviation for the set {600, 470, 170, 430, 300} has to be determined.

Start with the average of all the values. This is `A = (600+470+170+430+300)/5 = 394`

SD = `sqrt((1/5)*((600 - 394)^2 + (470 - 394)^2 + (170 - 394)^2 + (430 - 394)^2 + (300 - 394)^2))` `~~ 147.32`

The required standard deviation is 147.32
