Answer:
Now we can estimate the population variance with the sample variance given by:
And replacing we got:
And the estimator for the population deviation is given by :
Step-by-step explanation:
For this case we have the following data given:
1.83,1.85,1.79,1.73,1.69,1.74,1.76,1.70
First we need to calculate the mean with the following formula:
And replacing we got:
Now we can estimate the population variance with the sample variance given by:
And replacing we got:
And the estimator for the population deviation is given by :
