Answer:


And we can find the probability with this difference:

Step-by-step explanation:
For this case we have the following info given:
represent the sample size
the proportion of interest
We want to find the following probability:

We can use the normal approximation for this case since np >10 and n (1-p) >10
For this case we know that the distribution for the sample proportion is given by:

And we can use the following parameters:


And we can apply the z score formula given by:

And using this formula we got:


And we can find the probability with this difference:

The 2002 was the the foo=x2 was right
As a = 0 , there is no sign . Its only 0. Thus the answer is (c)
