Answer:
The distribution of the sample data will approach a normal distribution as the sample size increases.
Step-by-step explanation:
Central limit theorem states that the mean of all samples from the same population will be almost equal to the mean of the population, if the large sample size from a population, is given with a finite level of variance.
So, here Option C is not correct conclusion of central limit theorem -The distribution of the sample data will approach a normal distribution as the sample size increases.
We can say that the average of sample mean tends to be normal but not the sample data.
It means -1x - 2 = 3 those bars make all the number positive
The amount of money I spend putting gas in my car this week is
B = 3.079 G
where
' B ' is the number of Bux I spend on gas this week.
' G ' is the number of Gallons I buy this week.
-- The independent variable is 'G'. I can buy as few or as many gallons
as I want to.
-- The dependent variable is ' B '. It <em>depends</em> on how many gallons I buy.
Answer:
And if we solve for a we got
The highest total cholesterol level a woman in this 20–34 age group can have and still be in the bottom 1% is 91.771 mg per deciliter
Step-by-step explanation:
Let X the random variable that represent the cholesterol level of a population of women between 20-34, and for this case we know the distribution for X is given by:
Where
and
We want to find the highest value for the bottom 1% in the distribution, so we need to find a value a who satisfy the following conditions:
(a)
(b)
We can find a z value that satisfy the condition with 0.01 of the area on the left and 0.99 of the area on the right it's z=-2.33. And we can verify that on this case P(Z<-2.33)=0.01 and P(z>-2.33)=0.099
If we use condition (b) from previous we have this:
But we know which value of z satisfy the previous equation so then we can do this:
And if we solve for a we got
The highest total cholesterol level a woman in this 20–34 age group can have and still be in the bottom 1% is 91.771 mg per deciliter
Answer:
BC≈12.2
Step-by-step explanation:
As we know
24/sin(100°)=BC/sin(30°)
BC=sin(30°)×24/sin(100°)
BC=1/2×24/sin(100°)
BC=12/sin(100°)
BC=12.2 (approximately)
