Answer:
The 95% confidence interval for the true proportion of all voters in the state who favor approval is (0.4384, 0.5050).
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:
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 the true proportion of all voters in the state who favor approval is (0.4384, 0.5050).
20*6=120seconds +3600second in an hour so 3600*4=14400
1210+14400=14520
14520 is the answer I hope this helps!
Answer:
30 dollars
Step-by-step explanation:
packages-$12.36 x 2=24.72
broccoli-$1.98/2=.99
milk-$3.49
$24.72+.99=25.71
$25.71+$3.49=29.20
$29.20+.80=30.00
she payed with $30.00
Answer:
V = 882pi units^3
or approximately
2769.48 units^3
Step-by-step explanation:
The column of a cylinder is given by
V = pi * r^2 * h
We know the radius is 7 and the height is 18
V = pi * 7^2 *18
V =pi *49 *18
V =882 pi
If we want an approximate answer, we can approximate pi by 3.14
V = 3.14 * 882
V =2769.48
