Answer:
Incomplete question
First aspect of the question is typed below.
The shape of the distribution of the time required to get an oil change at a 20-minute oil-change facility
is unknown. However, records indicate that the mean time is 2l.2-minutes, and the standard deviation 3.5 minutes.
Explanation:
Employees bonus $50
35 oil changes between 10:00 am to 12:00pm
n = 35
10% changes
So, the z - score can be calculated using
z-score = InvNorm(0.10)
z-score = -1.28
So, given that,
Standard deviation is 3.5minutes
σ = 3.5 minutes
Mean time is 21.2 minutes
μx = 21.2 minutes
Then,
σx = σ / √n
σx = 3.5 / √35
σx = 0.5916 minutes
Then, Z score can be written as
Z = (x - μx) / σx
-1.28 = (x - 21.2) / 0.5916
Cross multiply
-1.28 × 0.5916 = x - 21.2
-0.7573 = x - 21.2
x = 21.2 - 0.7573
x = 20.443 minutes
There is a 10% chance of being at or below a mean oil-change time of 20.44 minutes
Answer:
the monopolist must lower price on all units sold and not just on the last unit sold.
Explanation:
A monopoly is a market structure which is typically characterized by a single-seller who sells a unique product in the market by dominance. This ultimately implies that, it is a market structure wherein the seller has no competitor because he is solely responsible for the sale of unique products without close substitutes.
Any individual that deals with the sales of unique products in a monopolistic market is generally referred to as a monopolist.
Marginal revenue can be defined as the additional amount of money that is gained or generated by a business firm from the sales of an additional unit of a product or service. Graphically, a change in the value of the total revenue curve at a given point gives the marginal revenue.
A price refers to the amount of money a customer or consumer buying goods and services are willing to pay for the goods and services being offered. The price of goods and services are primarily being set by the seller or service provider.
For a monopolist, the marginal revenue (MR) of a product or service is less than price because the monopolist must lower price on all of the units sold rather than lowering price on the last unit sold only.
Hence, the lower price applies to all units sold by a monopolist.
If the Central Banks decides to increase the discount rate. Then the commercial banks are less likely to borrow from the federal reserves. The Central Bank has the authority to increase and decrease discount rates in order to monitor the inflation rates of money as well as the prices of basic commodities
Answer:
(A) Stock A
Explanation:
A greater standard deviation is interpreted as a volatile stock. The price of the investment changes over time with a broad range, which is undesarible for the management of investment portafolios. There is also a correlation between risk and estimated return, when the commercial activity related with the stock has a stable performance, is commonly secure, and that is the reason why is offered a low rate of return.
In comparision with the second option, the Stock A has a greater volatility and higher return rate.
