The distribution of resistance for resistors of a certain type is known to be normal, with 10% of all resistors having a resistance exceeding 10.256 ohms and 5% having a resistance smaller than 9.671 ohms. What are the mean value and standard deviation of the resistance distribution? slader

Explanation:

Formula for the given probability is as follows.

            = 0.10

        = 0.10

According to the normal table area we have,

           P(z < 1.28) = 0.10

Hence,  

              .......... (1)

Also, the given probability is as follows.

            = 0.05

          = 0.05

Hence,    

                ....... (2)

Now, substitute the value of from equation (1) into equation (2) as follows.

              = 0.2

Putting the value of into equation (2) we will find the value of as follows.

                       =

                       = 10

Thus, we can conclude that the value of   is 0.2 and the value of is 10.
