please help me in this q 3.4  que 3, 4 

if sample variance consider range between 47 -48 then and I found ans of que  3 is  47.22 is right then why its square root is wrong in ans of que 4 which for sample standard deviation

as I  shared attachment please go through

Hello,

If you will calculate sample variance, you will get the value as 47.655 approximately. Take the square root of sample variance, you will get 6.903 approximately.

Thanks

But mam , if we taken range sample varience 47-48 then we should accept square root of 47-48 which fall under 6.85 -6.9 .

you can see my ans. of  que 3 (sample variance)  is right and I taken square root of it to get standard deviation which is wrong how it is possible
