You can put this solution on YOUR website! Suppose the test scores of 600 students are normally distributed with a mean of 76 and
standard deviation of 8. The number of students scoring between 70 and 82 is
-------
z(70) = (70-76)/8 = -3/4
z(82) = (82-76)/8 = +3//4
------------------
P(70< x <82) = P(-3/4< z <+3/4) = 0.5467
