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).
Answer:
Step-by-step explanation:
The total number of apples produced at the apple harvest is 2,350kg.
1 kg = 1000 grams. Therefore,
2350 kg = 2350 × 1000 = 2350000kg
A farmer packs 36 apples in the box. If one apple weighs approximately 250 grams, the total weight of 36 apples would be
36 × 250 = 9000 grams
Therefore, the number of boxes that are needed to pack the apples would be
2350000/9000 = 261.11
It means that 262 boxes would be needed.

The actual height of building is 1800 feet.
Step-by-step explanation:
Given,
Height of building in model = 3 inches
Scale used by engineer;
1 inch = 600 feet
Therefore;
Actual height of building = Height in model * Scale used
Actual height of building = 3 * 600
Actual height of building = 1800 feet
The actual height of building is 1800 feet.
