Answer:
0.708
Step-by-step explanation:
A great way to solve for probability is to create a fraction.
In our case, we can see that 17 out of 24 times they made it.
17/24 is our fraction.
Since the viniculum in a fraction represents division, we really have 17 divided by 24.
That is 0.7083.....
Rounding gives 0.708 as our final answer.
If you multiply 25×6×4 you should get 600.
hope this helps!

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
