Answer 1

Answer:

first you need to make correct class interval that will be

Subtract 0.5 from lower limit and add 0.5 to upper limit

0.5—200.5

200.5—400.5

400.5—600.5

600.5—800.5

800.5—1000.5

now see the frequency given for each column:

formula of mode=L+{f1-f0/2(f1)-f2-f0}×h

f1= highest frequency

f0= the frequency above f1

f2= the frequency below f1

L= lower limit of the class interval of f1

h=difference between the lower and upper limit
