Aquality analyst wants to construct a control chart for determining whether three machines, all producing the same product, are in control with regard to a particular quality variable. accordingly, he sampled four units of output from each machine, with the following results: machine measurements #1 17 15 15 17 #2 16 25 18 25 #3 23 24 23 22 what are the x-bar chart three-sigma upper and lower control limits? multiple choice 24 and 16 23.16 and 16.84 23.29 and 16.71 23.5 and 16.5 22 and 18

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

m∠a is 90°

m∠b is 40°
