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

47 - 90 = 43

43 - 180 = x

x = 137

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
