A population is normally distributed with a mean of 100 and a standard deviation of 10. For samples of size 25, what is the probability of randomly sampling and finding a sample mean of 99 or more

The value 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 standard deviation of the sampling distribution is  

=>      

=>      

=>      

Generally the probability of randomly sampling and finding a sample mean of 99 or more is mathematically represented as

Here  

=>    

From the z table probability of  (Z <  -0.5  ) is  

Generally  

=>
