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
Answer:
10.91%
Step-by-step explanation:
Take your number: 10.9091

That is 2 decimal places
(if your teacher doesn't want it rounded then just 10.90%)
