over a long time, cable from acme cable co has a mean strength of 37.5 ksi with a known population standard deviation of 1 ksi. find the probability that a random piece of th ecable has a strength x lower than 36.0 ksi

The value is

Step-by-step explanation:

From the question we are told that

 The mean is  

   The standard deviation is  

Generally the probability that a random piece of the cable has a strength x lower than 36.0 ksi is mathematically represented as

From the z table the probability of   is  

So

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)

step-by-step explanation:

2 x 503
