If the mean GPA among students is 3.25 with a standard deviation of 0.75, what is the probability that a random sample of 300 students will have a mean GPA greater than 3.30

The value is  

Step-by-step explanation:

From the question we are told that

   The mean GPA is  

   The standard deviation is

    The sample size is  n  =  300

Generally the standard error of mean is mathematically represented as

=>  

=>  

Generally the  probability that a random sample of 300 students will have a mean GPA greater than 3.30 is mathematically represented as

From the z table the probability of  (Z >  1.155 ) is
