Answer 1

Answer:

Step-by-step explanation:

a)  

There are three columns (135−140),(140−145),(145−150) who represent height more than or equal to 135cm but less than  150 cm

So, No. of students that have height more than or equal to 135cm but less than 150cm=14+18+10=42

(b)  

From histogram least number of students in any class interval are 4

The least number of students are in the class interval  = 150−155.

(c)  

Class size = upper limit - Lower limit

=130−125=5 is the class size.

(d)  

There are three columns (125−130),(130−135),(135−140) who represent height less than 140cm

Students that have height less than 140cm=6+8+14=28
