Answer:
![\hat p_1 -\hat p_2 \pm z_{\alpha/2} SE](https://tex.z-dn.net/?f=%5Chat%20p_1%20-%5Chat%20p_2%20%5Cpm%20z_%7B%5Calpha%2F2%7D%20SE)
And for this case the confidence interval is given by:
![0.11 \leq p_1 -p_2 \leq 0.39](https://tex.z-dn.net/?f=0.11%20%5Cleq%20p_1%20-p_2%20%5Cleq%200.39)
Since the confidenc einterval not contains the value 0 we can conclude that we have significant difference between the two population proportion of interest 1% of significance given. So then we can't conclude that the two proportions are equal
Step-by-step explanation:
Let p1 and p2 the population proportions of interest and let
and
the estimators for the proportions we know that the confidence interval for the difference of proportions is given by this formula:
![\hat p_1 -\hat p_2 \pm z_{\alpha/2} SE](https://tex.z-dn.net/?f=%5Chat%20p_1%20-%5Chat%20p_2%20%5Cpm%20z_%7B%5Calpha%2F2%7D%20SE)

Answer:
corresponding angles have the same (measure)
Step-by-step explanation:
So in the figure above, as you move points A or B, the two corresponding angles always have the same measure.
Y = 3x - 1 when x = -1
When the problem tells you what x is, put it into the problem:
y = 3(-1) -1
Solve the parentheses:
y = -3 -1
Now do the rest of it:
y = -4

Answer:
Step-by-step explanation:
area of the square =10*10=100
area of the circle =pi r^2=pi*1^2=3.142
part a
p(hitting the circle =3.142/100=0.03142 Which is closer to 0
part b
p( hitting the white portion ) =1-0.03142=0.96858 which is closer to 1
