Step-by-step explanation:
Information given
represent the number of men with smartphone
represent the number of women with smartphone
sample of men selected
sample of women selected
represent the proportion of men with smartphone
represent the proportion of women with smartphone
represent the pooled estimate of p
z would represent the statistic
represent the value
Part a
We want to test if we have difference in the proportion owning a smartphone between men and women, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
Part b
The statistic for this case is given by:
(1)
Where
Part c
Replacing the info given we got:
Part d
For this case we see that so then the answer for this cae would men
Answer:
Step-by-step explanation:
3+1/2x=0
1/2x=-3
2(1/2)x=(-3)2
x=|-6|
x=6 km
7. 2x+6x+8 = 32
8x+8=32
-8 -8
8x=24
— —
8 8
X=3
5. 34 because 4 and 2 are the same angle
3. 2x+24=146 is x=61
4.symetric property
6. 4 is 110 since it is equal to two and 1 is 70 since 180 - 110 is 70 and 3 is equal to 1
1.refective property
2. 2y/5
