Answer:
Not independent
Step-by-step explanation:
This problem involves independence criteria for conditional probabilities.
The two events will be independent if P(A/B)=P(A) or P(B/A)=P(B)
Let us assumes that event A is for student attending private college and B is for student graduating in four years.
So we are given the following probabilities
P(A)=0.20
P(B)=0.55
P(B/A)=0.79
As we can see that P(B/A)≠P(B) so the events A and B are not independent.
So based on the above results we can say that "attending a private college or university" is not independent of "graduating in four years". Thus the two events "attending a private college or university" and "graduating in four years" are dependent.
Answer:
now to get your samples on the division all you need to do is let me know what you mean he's actually once you get your me then you subtract you're mean from the values you're giving each of them then you squirt them to get your sample variance then once you get your sample rehearsal you not look for the squirrels which will not give us sample standard deviation so to do your own to do that of population and standard deviation you have to about the formula which is on the have to apply that will give you answers to 4 so I can do the square root so that she can do the square root
Both the numerator and the denominator are divisible by 2.
(4/2)/(10/2) so the simplest form would then be 2/5
Your answer is: 2/5
Answer:
NO!
Step-by-step explanation:
They are not equivalent. We can check this. If you rewrite them as fractions 13/14 and 1/2, you can cross multiply and see if they are equal. Which they are not. Also, you could just guess.... think of 13:14 as 13 out of 14. And 1:2 as 1 out of 2. You can tell that 13/14 is much greater than 1/2.
