find the mean and standard deviation for each uniform continuous model-
U(3, 12) mean: 7.5
U(80, 250) mean: 165
U(4, 93) mean: 48.5
i need the standard deviations for each round to the 4 decimal place

The standard deviation of the uniform distribution is:
σ=(b−a)/√12U(3, 12)
σ = (12−3)/√12 = 9/√12 = 2.5981U(80, 250)
σ = (250−80)/√12 = 170/√12 = 49.0748U(4, 93)
σ = (93−4)/√12 = 89/√12 = 25.6921Ответ:
so you need to calculate the mean ( average) and then calculate the MAD ratio
see attached picture for how to calculate the MAD:
