Answer:
Mean=[tex]0.17[/tex] [tex]mm[/tex]
Variance=[tex]2*10^{-4}[/tex] [tex]mm^{2}[/tex]
Step-by-step explanation:
Given is the uniform distribution
x=0.15,y=0.19
where x and y are lower and upper values.
mean=(x+y)/2
mean=(0.19+0.15)/2
Mean=0.17 mm
Now using equation
variance =[tex]((b-a+1)^{2}-1) /12[/tex]
For variance take a=15,b=19
Variance=[tex]((19-15+1)^{2}-1)/12[/tex]
Variance=2[tex]*10^{-4}[/tex] [tex]mm^{2}[/tex]
