Answer 1

Answer:

The sum of lower limits of the median class = 50

The sum of lower limits of the modal class = 70

Step-by-step explanation:

Class interval             Frequency (fi) Cumulative frequency (cf)

0−10                              20                            20

10−20                            30                            50                                            

20−30                           24                             74

30-40                            40                             114

40-50                             18                             132  

Cumulative frequency /  2 = 132 /  2 = 66

66 lies between 20 - 30 class

∴ Median class = 20 - 30

Frequency is high in class 30 - 40  so 30 - 40 is the model class.

The sum of lower limits of the modal class 40 + 30 = 70

The sum of lower limits of the median class 20 + 30 = 50
