Question

Find lower boundaries and upper boundaries of classes from consecutive class marks 0.34 , 0.54

Answer 1

Answer:

Step-by-step explanation:

Class Size = Difference between consecutive class marks = 54 - 34

Class Size = 20

1st interval

Lower Class Boundary = 34 - 20/2 = 24

Higher Class Boundary = 34 + 20/2 = 44

2nd interval

Lower Class Boundary = 54 - 20/2 = 44

Higher Class Boundary = 54 + 20/2 = 64

So the class limit of 2 intervals are

1) 24, 44

2) 44, 65
