a . The test statistic is -1.160740861
b. The p value is 0.2457473
Let the point estimate be 'a'. The formula for test statistic is:
Z = (a - p) / √ { [ p×(1-p) ]÷n }
Point Estimate 'a' = 30/78 = 0.384615385
Z = (0.384615385
-0.45 ) / √[ (0.45 × 0.55) ] / 78
Z = -0.065384615
/ 0.056330071
Z = -1.160740861
Answer:
10.16%
Explanation:
The computation of the effective return for this investment is shown below:
Let us assume that we invested an amount in Australian dollars 100
The return is 8%
After one year, the amount is 108
Now the converting amount is 110.16 (108 × 102%)
Now the effective rate for this investment is
= 110.16 - 100
= 10.16%
Answer: The common constraints faced by project managers are project scope, cost and time.
Explanations:
The three main constraints faced by project managers are the project scope, cost and time. These constraints affect the quality of a project. In high quality projects, the product is delivered within its scope at the required budget and on time.
The constraints are usually connected to one another. For example, an increase in the project scope will require an increase in cost and time. Also, accelerating the project timeline may lead to a reduction in the project costs but also lower the scope.
A trade off in project occurs when one constraint is reduced so as to increase another constraint. For trade-offs to be successful, project managers should take time to scrutinize the organization's objectives and the expectations of the project by using a structure that allows the project manager look at other options for the constraints and find the greatest balance among the constraints and organizational goals.
Answer:
Businesses borrow more money.
Consumption increases.
Explanation:
The Federal Reserve is the body responsible for conducting monetary policy in the US. Monetary policy basically consists of two actions. The increase / decrease in the money supply in the economy and the increase / decrease in the interest rate. These actions may happen together, but they are technically independent.
When the Federal Reserve increases the supply of money in circulation, more money is circulated through loans and personal spending. This is considered a policy of stimulating the economy and can be done independently of interest rate changes, although the reduction of interest is also a stimulus monetary policy that can be done in conjunction with the increase in the money supply.
