SOLUTION: Find the mean and standard deviation for each uniform continuous model. (Round "mean" answers to 1 decimal place and "standard deviation" answer to 4 decimal places)

Question 1175433: Find the mean and standard deviation for each uniform continuous model. (Round "mean" answers to 1 decimal place and "standard deviation" answer to 4 decimal places)
Mean Standard Deviation
a.)U(3,10) 6.5
b.)U(80,230) 155
c.)U(2,90) 46

the means are correct
the sd is (b-a)/sqrt(12)
so the first is 7/sqrt(12), the second 150/sqrt(12), the third has variance 88^2/12 or sd 88/sqrt(12), and these may be rationalized.
