Answer:
B.
Explanation:
Apply the 68-95-99.7 rule
The rule supposed that;
68% of the data in a standard normal distribution falls within 1 standard deviation of the mean.
95% of the data in a standard normal distribution falls within 2 standard deviation of the mean.
99.7% of the data in a standard normal distribution falls within 3 standard deviation of the mean.
Evaluating
Given the mean as 110 and the standard deviation as 19 then;
68% of the scores will be between 110-19=91 & 110+19=129
95% of the scores will be between 110-2(19)= 72 & 110+2(19)=148
99.7% of the scores will be between 110-3(19)= 53 & 110 +3(19)= 167
Analysis
68% of the scores will lie between 91 and 129 points.
95% of the scores will lie between 72 and 148 points
99.7% of the scores will lie between 53 and 167 points.
