Answer:
My explanation -->
Step-by-step explanation:
Go over to the left on the -4 and up 5 times and mark a dot on it.
Next, go up half a mark from 0 and put a dot there.
Then, go over to the left between the -2 and -4 and go up 5 times.
Lastly, from the 0, go down half way until the next horizontal line and place a dot there.
1) At 95% Confidence interval the critical value is z0.025= 1.96 Margin of error = 0.02 Or, z0.025* sqrt(p(1 - p)/n) = 0.02 Or, 1.96 * sqr
We know that
The formula for combinations is
C=n!/[(n-r)!*r!]
where
n is the total number of objects you choose from
r is the number that you choose to arrange
in this problem
n=15 students
r=4 students
C=15!/[(15-4)!*4!]-----> C=15!/[11!*4!]---> (15*14*13*12*11!)/(11!*4*3*2*1)
C=(15*14*13*12)/(24)----->C=1365
the answer is
1365
