Answer 2

Step-by-step explanation:

13. Find the mode of the following frequency distribution

here the maximum frequency is 8 and the class corresponding to this frequency 4000-5000

so modal class is 4000-5000

l =4000,h=100,f1=18,fo= 4 f²=9

mode=l+(f1-fo) /(2f1-fo-f2) ×h

4000+(18-4) /(2×18-4-9) ×1000

4000+(14×1000) /(36-13)

4000+(14000/23)

4000+608.7

mode =4608.7
