The lengths of plate glass parts are measured to the nearest 1/10 mm. The lengths are discretely and uniformly distributed with values at every 1/10th mm, starting at 590.0 thru 590.9 mm. Determine the mean & variance of lengths.

Respuesta :

For uniform, the mean is:

x¯ = (590.0+590.9) 2
The variance is:
σ = sqrt [ (n2−1) /12  ]

 Where n=10.

The answer would be 590.45


I hope my answer has come to your help. Have a nice day ahead and may God bless you always!
