Answer:
The 95% confidence interval for those opposed is: (0.298, 0.334).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
For this problem, we have that:
1786 of the 2611 were in favor, so 2611 - 1786 = 825 were opposed. Then
95% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The 95% confidence interval for those opposed is: (0.298, 0.334).
It costs $189-(4×$20) which is $189-$80=$109
Answer:
16/3
Step-by-step explanation:
Okay, we can round each number to the nearest whole.
37.2 + 2583
Round 37.2
<span>If
the number after the decimal point is 5 or more, we round up, but if it’s 4 or
less, we round down.
</span>
The number is 2 so we round down to 37.
Now we add 37 + 2583, which equals 2620.
18.256 - 5.71
Again, look at the numbers after the decimal point.
For 18, it's 2, so we round down to 18. For 5, it's 7 so we round up to 6.
So we have:
18 - 6
Subtract:
12
-9.916 + 12.4
Again, look at the numbers after the decimal point.
For -9, it's 9, so we round up to -10, for 12, it's 4, so we round down to 12.
So we have:
-9 + 12
Add:
3
Answer:
x = 40
Step-by-step explanation:
x/4 = 10
x/4 x 4 = 10 x 4
x = 40
