By the Pythagoras theorem:-
h^2 = x^2 + x^2
(where h = hypotenuse)
h^2 = 2x^2
h = sqrt2 x
Answer:
which angle ??
if it is DEC Then it will be 75°
Answer:
But we need to calculate the mean with the following formula:
And replacing we got:
And for the sample variance we have:
And thi is the best estimator for the population variance since is an unbiased estimator od the population variance
Step-by-step explanation:
For this case we have the following data:
1.04,1.00,1.13,1.08,1.11
And in order to estimate the population variance we can use the sample variance formula:
But we need to calculate the mean with the following formula:
And replacing we got:
And for the sample variance we have:
And thi is the best estimator for the population variance since is an unbiased estimator od the population variance
