Answer:
1,3.5
Step-by-step explanation:
just did it in Edge
Answer:
0.04
Step-by-step explanation:
In this case we must use the following formula to be able to find the standard error, which would be the square root, of the probability for its complement divided by the population:
SE= 
Now, knowing that p = 0.552 and n = 160 we replace and we are left with:
SE =
SE = 
SE = 0.039
Which means that the standard error of the proportion is 0.04
You should get 53 degrees.
First, note that
Then

Consider all options:
A.

By the definition,

Now

Option A is true.
B.

By the definition,

Then

Option B is false.
3.

By the definition,

Now

D.

By the definition,

As you can see
and option D is not true.
