Answer:
The null hypothesis was rejected.
Conclusion: The proportions of orders completed on the day of receiving is more than 95%.
Step-by-step explanation:
The hypothesis can be defined as:
<em>H₀</em>: The proportions of orders completed on the day of receiving is not more than 95%, i.e. <em>p</em> ≤ 0.95.
<em>Hₐ</em>: The proportions of orders completed on the day of receiving is more than 95%, i.e. <em>p</em> > 0.95.
The significance level of the test is <em>α</em> = 0.025.
The sample size is, <em>n</em> = 500.
As the sample size is large, the sampling distribution of sample proportion can be approximated by the Normal distribution.
The mean and standard deviation of this distribution are:
The test statistic is:
The sample proportion is:
Compute the test statistic as follows:
The decision rule is:
If the <em>p</em>-value is less than the significance level <em>α</em> then the null hypothesis is rejected.
Compute the <em>p</em>-value as follows:
*Use a <em>z</em>-table.
The <em>p</em>-value = 0.0202 < <em>α</em> = 0.025.
The null hypothesis will be rejected.
<u>Conclusion</u>:
As the null hypothesis was rejected at 2.5% level of significance, it can be concluded that the proportions of orders completed on the day of receiving is more than 95%.
Answer:
The marginal revenue is
Step-by-step explanation:
From the question we are told that
The inverse demand for a downstream firm is
The cost of the critical input produced by upstream division is
The cost of the critical input produced by downstream firm is Cd(Q) = 10Q
Generally
The marginal revenue of the downstream firm - The marginal cost of the downstream firm = Net marginal revenue of downstream
i.e
Also
The marginal revenue of the downstream firm - The marginal cost of the downstream firm = Marginal upstream cost
i.e
So
Generally the total revenue of downstream firm is mathematically represented as
Here Q stands for quantity produced by the downstream firm and TR is the total revenue
=>
Generally the marginal revenue of the downstream firm is mathematically evaluated as
Generally marginal downstream first cost is mathematically evaluated as
Generally the net marginal revenue of the downstream firm is mathematically represented as
=>
Generally the marginal upstream cost is mathematically represented a
Generally this because
represents the quantity produced by the downstream firm and also Q is associated with the cost of the downstream quantity
So
=>
=>
So the net marginal revenue of the downstream firm is mathematically represented as
=>
=>
