Step 1

Preliminary calculations:

The probability distribution is constructed as follows. help_outlineImage Transcriptionclose(x-) (x-P(x) Computers (x) Households (P(x) | x-/i 300 0 0.3 -1.1 1.21 0.363 1 400 0.4 -0.1 0.01 0.004 2 200 0.2 0.9 0.81 0.162 100 0.361 3 0.1 1.9 3.61 (x-Px) 0.89 Ef=1,000 1.0 fullscreen
Step 2

a) Computation of Mean:

The mean is calculated as 1.1, from the calculations given below.

Step 3

b) Computation of variance:

The variance is calculated as 0.89, fro...
