Answer:
1.48 m
Step-by-step explanation:
In a class of 32 students
the mean height of the 14 boys is 1.56 meters.
the mean height of all 32 students is 1.515 meters.
Total number of students = 32
Mean height of all students = 1.515
We can obtain the sum of all student's height :
Number if students * mean height
= 32 * 1.515
= 48.48
Number of boys = 14
Mean height of boys = 1.56m
We can obtain the sum of all boys height :
Number if students * mean height
= 14 * 1.56
= 21.84
Number of girls :
All students - Number of boys
32 - 14 = 18
Sum of girls height :
48.48 - 21.84 = 26.64
Mean height of girls :
Sum of girls height / Number of girls
26.64 / 18
= 1.48 m
