Answer:
The 95% confidence interval for the population proportion is (0.1456, 0.2344). This means that we are 95% sure that the true proportion of employed American who say that they would fire their boss if they could is between 0.1456 and 0.2344.
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 population proportion is (0.1456, 0.2344). This means that we are 95% sure that the true proportion of employed American who say that they would fire their boss if they could is between 0.1456 and 0.2344.
Answer:
<h2> 112.3 square units</h2>
Step-by-step explanation:
Find the sketch of the triangle attached.
Area of the triangle =
Given PQ = 20, PR = 12 and ∠QPR = 68°
Area of the triangle = 1/2 * 20 * 12 * sin68°
Area of the triangle = 120sin68°
Area of the triangle = 112.26 square units
Area of the triangle ≈ 112.3 square units (to the nearest tenth of a square unit)

20 kg bag of bananas for 10 dollars
This is the given situation in which in every 20 kilogram of bananas, the costs is 10 dollars.
Now, let us calculate how much each kg of banana costs will. Let’s solve for the unit rate of this given data:
=> 20 kg bag of banana
=> 10 dollars = cost
Now, let’s divide this to get the answer that we need.
=> 20 / 10
=> 2 bananas per dollars = 2 banana/dollars
Or 10 / 20
=> 0.5 dollars/1kg of banana
