Answer: Standard deviation 6.0553

Explanation:

Mean = sum of values / N (number of values in set)

=(16+17+18+29)/4

=80/4

Mean is 20

Variance = ([tex](n_{1} -Mean)^{2} )+.... (n_{n} -Mean^{2} )[/tex]) / N-1 (number of values in set - 1)

=([tex](16-20)^{2}[/tex]+[tex](17-20)^{2}[/tex]+[tex](18-20)^{2} +(29-20)^{2}[/tex])/3

=36.66667

Variance for standard deviation is 36.66667

Standard Deviation σ = √Variance

=[tex]\sqrt{36.66667}[/tex]

=6.0553

Standard Deviation σ= 6.0553
