Answer:
Acitivy B should be crashed first by 2 days and Activity B has a crash cost per days of $25, it will be crashed for a total of $50.
Explanation:
activity A =
normal time (NT) = 5 days
Normal cost (NC) = $0
crash time (CT) = 3 days
Crash cost (CC) = $500
crash cost per day = [CC - NC]/[CT - NT] = $250/day
activity B:
normal time (NT) = 6 days
Normal cost (NC) = $0
crash time (CT) = 4 days
Crash cost (CC) = $50
crash cost per day = [CC - NC]/[CT - NT] = $25/day
activity C:
normal time (NT) = 8 days
Normal cost (NC) = $0
crash time (CT) = 3 days
Crash cost (CC) = $1000
crash cost per day = [CC - NC]/[ CT- NT] = $200/day
The activity that takes the least cost to speed up is the first one to be crashed. from the computations, activity B takes the least cost to speed up, so the project manager should crash activity B first by 2 days.
Therefore, Acitivy B should be crashed first by 2 days and Activity B has a crash cost per days of $25, it will be crashed for a total of $50.
Answer: $100 million
Explanation:
National Income (GDP) for a close nation is calculated as:
= Consumption + Investment + Government spending
Making investment the subject would give us:
Investment = GDP - Consumption - Government spending
= 400 - 150 - 150
= $100 million
Answer:
a) H0: u = presence of a unit root
HA: u ≠ presence of a unit root ( i.e. stationary series )
b) t stat = -0.064
c) We will reject the Null hypothesis and the next step will be to accept the alternative hypothesis
d) It is not valid to compare the estimated t stat with the corresponding critical value because a random walk is non-stationary while the difference is stationary because it is white noise
Explanation:
<u>a) stating the null and alternative hypothesis</u>
H0: u = presence of a unit root
HA: u ≠ presence of a unit root ( i.e. stationary series )
<u>b) performing the test </u>
critical value = -2.88
T stat = coefficient / std error
= -0.02 / 0.31 = -0.064
c) From the test, the value of T stat > critical value we will reject the Null hypothesis hence the next step will be to accept the alternative hypothesis
d) It is not valid to compare the estimated t stat with the corresponding critical value because a random walk is non-stationary while the difference is stationary because it is white noise
Answer:
The correct answer is: Distribution.
Explanation:
To begin with, the concept of distribution inside the marketing field and refering specifically to the internal marketing approach is understand as the way that the informatino of the marketing strategy is distributed inside the organization with all of the members that need to know that data in order to focus on the campaign and make it possible and effective so that the objectives are accomplished. That is why that the planning sessions, workshops, formal reports and personal conversations are part of the internal distribution that is necessary to implement the marketing strategy that the company tends to use.
