Answer:
The probability is 1.
Explanation:
Despite that the he distribution is positively skewed, the distribution of sample means of one-bedroom apartments will still be a a normal distribution based on Central Limit Theorem.
Since we have
μ = mean = 2200
SD = standard deviation = 250
n = sample size = 50
Therefore,
Standard error = SD ÷ √n
= 250 ÷ √50
= 250 ÷ 7.07106781186548
= 35.3553390593274 approximately 35.36
Standardize xbar to z = (xbar - μ) ÷ (SD ÷ √n)
Therefore, we have:
P(xbar > 1,950) = P(z > (1,950 - 2200) ÷ 35.36)
= P(z > - 250 ÷ 35.36)
= P(z > -7.07) = 1
Therefore, the probability of selecting a sample of 50 one bedroom apartments is 1 which can be said to be certain.
Answer:
The production range between 1120,000 and 150,000 is called Relevant range
correct option is c) relevant range
Explanation:
given data
normally produces = 120,000 to 150,000 units
to find out
The production range between 1120,000 and 150,000 is called
solution
The production range between 1120,000 and 150,000 is called Relevant range because there are 2 point
- if Craft, Inc. need to reduce fixed expenses then production volume is reduce less than 120000 unit
- if Craft, Inc. need to increase fixed expenses than production volume is increases more than 150000 unit
and if expected fixed expenses will not change than the production volume is 120000 units to 150000 units
so that production range between 1120,000 and 150,000 is called Relevant range
correct option is c) relevant range
Answer:
At least during the last couple of decades, service firms tend to generate sustained growth while manufacturing firms do not.
Explanation:
The last president that recorded a steady manufacturing growth rate was Bill Clinton.
Service firms are growing steadily and probably will continue to do it. While manufacturing firms have been slowing down, their growth rate (if any) is not very large during the past few years and that tendency has increased with the new trade barriers imposed by our government during the last couple of years.
Another thing that helps the growth of service firms is that when manufacturing firms or agricultural firms grow, they need more services, so service firms will grow even more.
The difference between the realized overheads and the estimated overheads is the total overhead cost.
<h3>What are total overhead costs?</h3>
Total overhead costs are identified as the costs related to administration, sales, marketing, and production. Before the total overhead costs are realized, a budget regarding estimated costs is prepared.
The calculation of the total overhead costs is actual overhead costs less the budgeted overhead costs.
Hence, the aforementioned statement regarding total overhead costs holds true.
