1.	Find the missing frequency ’x’ if mode = 74 C.I 20-30 30-40 40-50 50-60 60-70 70-80 frequency 2 3 1 4 x 8
Answer» ANSWER: x= 8 Step-by-step explanation: C.I f 40-50 5 50-60 x 60-70 15 70-80 12 80-90 7 As FORM given the MODE is 67 which lies in 60-70 therefore L= 60 Now as we know Hence, the MISSING frequency is 8.

Find the missing frequency ’x’ if mode = 74 C.I 20-30 30-40 40-50 50-60 60-70 70-80 frequency 2 3 1 4 x 8

Answer»

ANSWER: x= 8

Step-by-step explanation:

C.I f

40-50 5

50-60 x

60-70 15

70-80 12

80-90 7

As FORM given the MODE is 67 which lies in 60-70

therefore L= 60

Now as we know

Hence, the MISSING frequency is 8.
