Answer:
The proportion of people in your sample whose response is yes=40 people
Explanation:
<em>Step 1: Determine the statistical proportion that will say yes</em>
Proportion=40%=40/100=0.4
<em>Step 2: Determine the proportion in the sample that will say yes</em>
The proportion in the sample can be expressed as;
P=S×Z
where;
P=proportion in the sample
S=statistical proportion
Z=sample size
In our case;
P=unknown to be determined
S=40%=40/100=0.4
Z=100
replacing;
Proportion in the sample=0.4×100=40
The proportion of people in your sample whose response is yes=40 people

Answer:
The answer to this question is option C. $560
Explanation:
We can let the price of each hollow pine door = d and of each solid oak door = 2d.
Since each pine door = 40, d = 40, and the regular price of each solid oak door is (2)(4) = 80.
With a 25% discount, each solid oak door is 0.75(80) = 60.
So, the six oak doors cost 6 x 60 = 360 dollars, and the five pine doors cost 5 x 40 = 200 dollars. Thus, the total is 560 dollars.
Hence the answer is C
Answer:
$0.3 per machine hour
Explanation:
The computation of the variable maintenance cost per machine hour using the high low method is shown below:
Variable cost per machine hour = (High maintenance cost - low maintenance cost) ÷ (High machine hours - low machine hours)
= ($9,000 - $7,200) ÷ (20,000 machine hours - 14,000 machine hours)
= $1,800 ÷ 6,000 machine hours
= $0.3 per machine hour
