Answer 1

Answer:

Here , class width = 20

class mark = 70

Half of the class width =20 /2  =10

Upper limit of first class interval = 70 + 10 = 80

Lower limit of  first class interval = 70 – 10 = 60

Thus, class interval becomes 60 – 80

So, frequency distribution table

(a) Number of oranges weights more than 180 g = 1 + 1 = 2

(b) Number of oranges weights less than 100 g = 3 + 10 = 13
