Answer :
If four students measure their heights to be 130 cm, 130, cm, 138 cm, and 176 cm, then the average(mean) height of these students is 143.5cm.
To find the average (mean) height, follow these steps:
- The formula to find the average height is: Average height= Sum of all heights/ Total number of students.
- Substituting the values of the four students, we get the average height of these four students as (130+130+138+176)/4= 574/4= 143.5 cm
Hence, the average (mean) height of these students is 143.5 cm.
