Explanation / Answer

The above problem sloving by using r software

the formula for sample standerd deviation is,

s.d.= square root(sample variance)

so, define vector x for all 50 randam sample

find the sample variance

and square root of this sample variance is s.d.

x=c(0.98,0.82,0.91,0.98,0.75,0.87,0.88,0.76,0.84,0.83,0.81,0.76,0.78,0.79,0.74,0.81,0.84,0.92,0.75,0.73,0.81,0.96,0.85,0.79,0.83,0.87,0.81,0.93,0.75,0.82,0.96,0.74,0.86,0.82,0.88,0.87,0.82,0.85,0.87,0.91,0.86,0.75,0.83,0.86,0.94,0.87,0.81,0.79,0.78,0.82)
var=var(x)

[1] 0.004281796

hence, sample variance = 0.004281769

s.d.=sqrt(var)

s.d.

[1] 0.06543543

hence sample standerd deviation is 0.065
