Answer:
sample variances
Step-by-step explanation:
The pooled variance method is used to estimate the variance of several different population with different means, but are assume to have the same variance.
The weights represent the sample variances.
So the correct answer is
sample variances
It is a it is symmetric on both sides and it’s peak is at 3
Answer:
And we can find the probability with this difference:
And using the normal standard table or excel we got:
And the best answer would be:
0.3811
Step-by-step explanation:
Let X the random variable that represent the ratings of a population, and for this case we know the distribution for X is given by:
Where
and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
Using the z score we got:
And we can find the probability with this difference:
And using the normal standard table or excel we got:
And the best answer would be:
0.3811
