Given data,
161   150   154   165   168   161   154   162   150    151
 162   164   171   165   158   154   156   172   160   170
 153   159  161   170   162   165   166   168   165    164
 154   152  153   156   158   162   160   161    173   166
 161   159   162   167   168   159   158   153   154   159
The maximum and minimum height ranges of the pupils are also included in this table, along with information on which range the majority of the students fall in.
50 students make up the class as a whole.
The height range for a student in the class is between 150 and 155.
The height of a pupil in the class may not exceed 170 to 175 inches.
To determine the range in which the majority of students fall:
Students that are under 165 cm,
12 + 9 + 14
⇒   35
Percentage,
⇒%= 35 50  × 100     ⇒  %=70%
Therefore, it can be inferred from the following table that the minimum range of heights is 150–155 and the maximum range is 170–175 inches.
Additionally, it can be inferred from the data that more than 50% of the kids are under 165 cm in height.
Therefore the answer is option (1).
