Answer:
(D) $369.31 to $380.69
Explanation:
The formula is x ± t (s/√n)
x = 375
t = 2.010
s = 20
n = 50
Then,
375 ± 2.010 (20/√50)
= 375 ± 5.69

Answer:
c. It should process further because the reduction in the cost of the trees is irrelevant.
Explanation:
For the purpose of this Decision,
Benefit of processing further = Sales Value after processing – Sale Value before processing – Further Processing costs
Cost of acquiring trees is a sunk cost already incurred and hence is not relevant
Hence, benefit of processing = (0.80-0.20)*350 – 50
= $160
Hence, the answer is
c. It should process further because the reduction in the cost of the trees is irrelevant.
The reason why business fail is because they find it extremely hard to compete with the well known business. for example a man that opens up a buisiness that sells soap and decides to name the soap and company labbi but everyone goes to dove because it's more well known and been out for years and delivers high quality
Answer:
$0.013
0.010724
Explanation:
Given that :
Mean, m = 36500
Standard deviation, s = 5000
Refund of $1 per 100 mile short of 30,000 miles
A.) Expected cost of the promotion :
P(X < 30,000)
Using the Zscore relation :
Zscore = (x - m) / s
Zscore = (30000 - 36500) / 5000
= - 6500 / 5000
= - 1.3
100 miles = $1
1.3 / 100 = $0.013
b. What is the probability that Grear will refund more than $50 for a tire?
100 miles = $1
$50 = (100 * 50) = 5000 miles
Hence, more than $50 means x < (30000 - 5000) = x < 25000 miles
P(x < 25000) :
(25000 - 36500) / 5000
-11500 / 5000
= - 2.3
P(z < - 2.3) = 0.010724 (Z probability calculator)
