If a certain machine makes electrical resistors having a mean resistance of 40 ohms and a standard deviation of 2 ohms, what is the probability that a random sample of 25 of these resistors will have a combined resistance of less than 1010 ohms?

The probability is  

Step-by-step explanation:

From the question we are told that

   The mean is  

   The standard deviation is  

   The sample size is  n = 25

    The combined resistance is  

Generally the sample mean is mathematically represented as

=>  

=>  

Generally the standard error of the mean is mathematically represented as

=>  

=>  

Generally the probability that a random sample of 25 of these resistors will have a combined resistance of less than 1010 ohms is mathematically represented as

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