Answer:
c) $40,000 to buy the part
Explanation:
For computing the better off first we have to compute the per unit cost which is shown below:
= Direct material per unit + Direct labor per unit + variable overhead + applied variable overhead
= $12 + $25 + $13 + $30 × 30%
= $12 + $25 + $13 + $9
= $59
The difference cost would be
= $59 - $55
= $4
Now the better off would be
= Number of units × difference cost
= 10,000 units × $4
= $40,000
The correct answer would be B. This is because you are spending more money aka $12,000 which would result in you having less money than if you bought one for $8,000!
Answer: c. There is sufficient evidence to support the claim that the mean is greater than 23 miles per gallon.
Explanation:
When doing a research, there are 2 Hypothesis one must come up with which are the Null Hypothesis and the Alternative hypothesis.
The Null Hypothesis should state that there is no relationship between the variables which in this case would mean that new sedan, the Libra, will <em>not</em> average better than 23 miles per gallon in the city.
The Alternative Hypothesis on the other hand affirms the belief of the researcher which in this case is that new sedan, the Libra, <em>will </em>average better than 23 miles per gallon in the city.
As the null hypothesis was rejected by the evidence, it means that indeed the Libra mean is greater than 23 miles per gallon.
