Answer:
102 students
Step-by-step explanation:
Note that 65% and 71% are both 1 standard deviation from the mean (71%). According to the empirical rule, 68% of scores lie within 1 std. dev. of the mean.
68% of 150 students would be 0.68(150 students) = 102 students
The answer is 12. All you had to do was divide.
So, 30 divided by 2.5 equals 12.
I hope this helps!
