12. Calculate the standard deviations for the following set of measurements: a) 10, 8, 6, 0, 8, 3, 2, 8, 0 b) 20, 1, 2, 5, 4, 4, 0

Need more information to solve it

The great thing about this problem is they give you everything you need to solve it easily. so the expression is: 12h+30w12h+30wand so everywhere you have an “h” you place 66. and everywhere you have a “w” you place 33. then the expression will look like this: 12(66)+30(33)12(66)+30(33)from here you multiply and then add. getting the following of: $785,862hope this
