Sample Size = n = 18
Proportion of processor which meet specifications = p = 90% = 0.90
We are given that the Binomial distribution is valid for the given case. The mean value of the binomial distribution can be calculated as:
Mean = np
Using the values of n and p for given case, we get:
Mean = 18 x 0.90 = 16.2
So, on average 16.2 processor will meet the specifications
Printed pages in 11 minutes = 33 pages
Printed pages in a minute = 33/11
= 3 pages/minute
