D. Identify which tasks are primary and which are dependent.
Answer:
E) Only Machine B is acceptable
Explanation:
The computation is shown below;
<u>For Machine A </u>
<u>Year Cash Flow PV Factor PV of Cash Flow </u>
0 -$9,000 1 -$9,000
1 $5,000 0.8696 $4,348
2 $4,000 0.761 $3,044
3 $2,000 0.6575 $1,315
NPV -$293
<u>Machine B </u>
<u>Year Cash Flow PV Factor PV of Cash Flow </u>
0 -$9000 1 -$9,000
1 $1,000 0.8696 $869.6
2 $2,000 0.761 $1,522
3 $11,000 0.6575 $7,232.5
NPV $624.1
As we can see that from the above calculations that the npv for machine A is in negative so the same should not be accepted but for machine the npv is in positive so the same should be accepted
Answer:
The 95% confidence interval for the true weight is 1.4103 and 1.41587 grams.
Explanation:
If we sorted by ascending order the three weighings given and we asumme these 3 weighings as extreme values and mean, we can calculate the 95% confidence interval. Using the formula for Normal distributions we know that 95% intervals are 1,96 times standard deviation from the the mean, then Mean (1.4131) ± 1.96*Standard deviation (0.001) = 1.4103 and 1.41587
