Answer:
a)
With:
b)
c)
d)
Step-by-step explanation:
For this case we know the following propoertis for the random variable X
We select a sample size of n = 81
Part a
Since the sample size is large enough we can use the central limit distribution and the distribution for the sampel mean on this case would be:
With:
Part b
We want this probability:
We can use the z score formula given by:
And if we find the z score for 89 we got:
Part c
We can use the z score formula given by:
And if we find the z score for 75.65 we got:
Part d
We want this probability:
We find the z scores:
To find this out, divide 35 by 60:
35/60 = .583333333333
So 35 is 58.3% of 60.
Hope this helps!
Is this a rise over run question
First do (30×20)/2 + 20×25 + 35×42 + (42×25)/2
it should give you a total of 2795 cm
