Answer:
The Correlation analysis “R” is measured to compute the strength of relationship among variables. Moreover, the value of correlation is calculated among -1 to +1. Which implies that if the computed value is near to -1 then there will be strong but negative relation and if near to +1 then it is strong but relation among the variable. However zero is consider as neutral point.
A. The computed value of correlation is - 0.772. The value identifies that that there is a strong but negative association among the variables (GDP and infant mortality rate).
B. The correlation analysis cannot computed among the variables continent and GDP because "continent" is a categorical variable not quantitative.
C. The computed value of correlation is higher than 1. Thus, the statement implies that there is a very strong relationship among life expectancy and GDP which is incorrect. As the association cannot be higher than 1.
D. There is a strong relationship among literacy rate and GDP as the relationship is nearer to 1. Furthermore, the association among literacy rate and GDP doesn’t suggest the causation.
E. The computed correlation among the variables is 0.90. Which indicated that the variables goes up. That is, when the GDP goes down the import is also decrease and when GDP increases the import increases Thus, the there is a positive correlation.
Answer:
B) the wages received for the fifth day of work.
Explanation:
Marginal benefit is the increment in benefit generated by an increase by one unit of output. In this situation, the marginal benefit is given by difference in wage of working five days a week from the wage of working four days a week. Therefore, the marginal benefit is the wage received for the fifth day of work.
The answer is alternative B)
Answer:
$5,225,417
Explanation:
first payment 800000
1 quarter 250000
2 quarters 254000
3 quarters 258064
4 quarters 262193
5 quarters 266388
6 quarters 270650
7 quarters 274981
8 quarters 279380
9 quarters 283851
10 quarters 288392
11 quarters 293006
12 quarters 297694
13 quarters 302458
14 quarters 307297
15 quarters 312214
16 quarters 317209
17 quarters 322284
18 quarters 327441
19 quarters 332680
20 quarters 338003
11% = (1 + i/4)⁴
i = 0.106
quarterly interest = 2.65%
Now we need to determine the present value of this annuity and our discount rate is 2.65%. I will use an excel spreadsheet to determine the present value of the 20 quarterly payments and then add the initial payment.
$4,425,417 + $800,000 = $5,225,417
