Question

Five people were asked approximately how many hours of TV they watched per week. Their responses were as follows. 6 4 6 7 8 1

Answer 1

Answer:

-0.2,-2.2,-0.2, 0.8, 1.8

Step-by-step explanation:

Given :Five people were asked approximately how many hours of TV they watched per week.

Their responses were as follows. 6 4 6 7 8

To Find : Find the deviations from the mean for these five data values

Solution :

Mean = $\frac{\text{Sum of all observations}}{\text{Total no. of observations}}$

Mean = $\frac{6+4+6+7+8}{5}$

Mean = $6.2$

The deviations from the mean for these five data values: 6-6.2,4-6.2,6-6.2,7-6.2,8-6.2=-0.2,-2.2,-0.2, 0.8, 1.8

Hence the deviations from the mean for these five data values is -0.2,-2.2,-0.2, 0.8, 1.8
