Find (a) the range and (b) the standard deviation of the data set 0.5,2.0,2.5,1.5,1.0,1.5 . round to the nearest hundredth if necessary.

a.2

b.0.65

Step-by-step explanation:

Given data

0.5,2.0,2.5,1.5,1.0,1.5

Highest value=2.5

Lowest value of data=0.5

Range=Highest value-Lowest value=2.5-0.5=2

Sum of given data=0.5+2+2.5+1.5+1+1.5=9

Total number of observations=n=6

Mean=

Using the formula

x    

0.5         1

2.0         0.25

2.5          1

1.5            0

1.0            0.25

1.5            0

Standard deviation=

S.D=

just pick what you think i need more time let me know if this
