Answer:
the answers are below:
Step-by-step explanation:
a. null hypothesis:
H0: Pw - Pm = 0 (so Pw = Pm)
alternate hypothesis:
H1: Pw - Pm > 0 (so Pw > Pm)
<u>where Pw is the proportion of women</u>
<u>Pm is the proportion of men</u>
b.) proportion of women = o.40
proportion of men = 0.32
sample size of women = 20
sample size of men = 25
![z = 0.4 - 0.32/ \sqrt{((0.4 *0.6)/20) * (0.32 * 0.68)/25)}](https://tex.z-dn.net/?f=z%20%3D%200.4%20-%200.32%2F%20%5Csqrt%7B%28%280.4%20%2A0.6%29%2F20%29%20%2A%20%280.32%20%2A%200.68%29%2F25%29%7D)
![z = 0.56](https://tex.z-dn.net/?f=z%20%3D%200.56)
c.) p value =
p(z>0.56)
= 0.7123
= 1 - 0.7123
= o.2877 which can be approximated to be 0.288
d. alpha value was set at 0.05
the p value is greater than alpha.
therefore it is not statistically significant.
we conclude that the proportion of roman catholic women is not greater than men.
The angle of a a triangle is 180 so you do
180 - 44 = 136
136 - 31 = 105
so y = 105
6.4^4 (b^3) or as shown in photo
9514 1404 393
Answer:
h = 12 m
Step-by-step explanation:
Sides of the triangle are proportional.
(3.6 m)/(1.2 m) = h/(1.2 m + 2.8 m)
(4 m)(3.6/1.2) = h . . . . . multiply by 4 m
h = 12 m
