The results of a test that follows a normal distribution have a mean value of 10.0 and a standard deviation of 1. Find the probability that a single reading is between 8 and 10

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 single reading is between 8 and 10 is mathematically represented as

=>    

=>  

From the z table  the area under the normal curve to the left corresponding to  1 and  -2  is  

and

=>
