The heights in feet of people who work in an office are as follows. use the range rule of thumb to find the standard deviation. round results to the nearest tenth.

5.9 5.7 5.5 5.4 5.7 5.5 5.6 6.2 6.1 5.5
question 4 answers

a.1.2
b.0.1
c.0.2
d.0.5

Step-by-step explanation:

mean=(5.9+5.7+5.5+5.4+5.7+5.5+5.6+6.2+6.1+5.5)/10=57.1/10=5.71

we assume mean=5.7

x    mean  |x-mean| (x-mean)^2

5.9   5.7      0.2         0.04

5.7   5.7         0            0

5.5   5.7      0.2         0.04

5.4   5.7      0.3         0.09

5.7   5.7         0             0

5.5   5.7      0.2         0.04

5.6   5.7      0.1          0.01

6.2   5.7      0.5         0.25

6.1    5.7      0.4         0.16

5.5   5.7      0.2         0.04

                                0.63

standard deviation=√((0.63)/10)=√(0.063)≈0.251

so c
