Answer:
And if we solve for a we got
So the value of height that separates the bottom 20% of data from the top 80% is 23.432.
Step-by-step explanation:
Let X the random variable that represent the heights of a population, and for this case we know the distribution for X is given by:
Where and
For this part we want to find a value a, such that we satisfy this condition:
(a)
(b)
As we can see on the figure attached the z value that satisfy the condition with 0.20 of the area on the left and 0.80 of the area on the right it's z=-0.842
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
So the value of height that separates the bottom 20% of data from the top 80% is 23.432.
Answer:
28 feet farther than 1st ball.
Step-by-step explanation:
We have been given that Susan threw a softball 42 yards on her first try and yard on her second try.
To find second ball is how much farther from the 1st ball, we will subtract 42 yards from yards.
Let us have a common denominator.
Therefore, Susan thrown the second ball 28 feet farther from the 1st ball.
