Suppose the probability density function of the length of computer cables is f(x)= 0.1 from 1200 to 1210 millimeters. A) Determine the mean and standard deviation of the cable length. B) If the length specifications are 1195 < x < 1205 millimeters, what proportion of cables is within specifications?

a) Mean = 1205

Standard Deviation = 2.89

b) P( 1195 < x < 1205) = 0.5

50% of the cables lie within the given specification.

Step-by-step explanation:

We are given the following information in the question:

a = 1200, b = 1210

We are given a uniform distribution.

a) Mean:

Standard Deviation:

b) P( 1195 < x < 1205)

50% of the cables lie within the given specification.
