Answer 2

Step-by-step explanation:

Data in tabular form using tally marks.

115 cm = 1 student/s

116 cm = 7 student/s

117 cm = 3 student/s

118 cm = 2 student/s

119 cm = 4 student/s

120 cm = 3 student/s

121 cm = 4 student/s

122 cm = 1 student/s

123 cm = 2 student/s

124 cm = 3 student/s

Total Students= 30 Students
