Answer:
The standard deviation = 1.9
Step-by-step explanation:
standard deviation, ρ = sqrt ( )
Where u is the mean of the data, each given value, and N is the number of data given.
Mean, u =
= 5.2
So that;
=
= 0.64
=
= 0.04
=
= 10.24
=
= 0.04
=
= 7.84
Sum = 18.8
So that;
=
= 1.9391
= 1.9
The standard deviation of the given data is 1.9
