Answer:
And taking the square root we got the sample deviation:
Step-by-step explanation:
For this case we have the following datset given:
0.83 1.39 1.39 1.03 0.66 1.26 1.39 1.18 1.41 1.19 1.15
We need to find the range, and the range is defined by:
And replacinng we got:
Then we can find the sample variance, but firt we need to find the sample mean with this formula:
And replacing we got:
Now we can find the sample variance with this formula:
And replacing we got:
And taking the square root we got the sample deviation:
