Question

kevin · Answer

standard deviation = sqrt(variance)

mrnood · Answer

OK - there are a number of steps you need to take to work out this value

First of all can you work out the MEAN of all the values

Post it here and I will help with th enext step...

kevin · Answer

variance = $$\frac{ \sum_{i=1}^{n} f(x - \mu )^2}{ n }$$

mrnood · Answer

NOTE - you are asked for the POPULATION SD

(More often you will be faced with SAMPLE SD)

The first thing you need is the mean - but before that @iyanlak1 please respond

This is a process you should DO yourself - rather than let @Kevin do it for you.
Once oyu have done it you will understand it - then you can use a calculator or website for future calculations.
