Answer:
Applied Overhead is higher than actual overhead. Hence, manufacturing overhead is $ 4,000
Explanation:
Given data:
estimated overhead = $2,40,000
Labor cost =$2,80,000
Direct labor cost = $3,00,000
= $ 0.80 per direct labor cost
=$ 2,24,000
Actual Overhead cost = $ 2,20,000
Applied Overhead is more than actual overhead. Hence, manufacturing overhead is $ 4,000.
Answer:
1) We need a random sample. For this case we assume that the sample selected was obtained using the simple random sampling method.
2) We need to satisfy the following inequalities:
So then we satisfy this condition
3) 10% condition. For this case we assume that the random sample selected n represent less than 10% of the population size N . And for this case we can assume this condition.
So then since all the conditions are satisfied we can conclude that we can apply the normal approximation given by:
So then the answer for this case would be:
a. Yes.
Explanation:
For this case we assume that the question is: If in the experiment described we can use the normal approximation for the proportion of interest.
For this case we have a sample of n =25
And we are interested in the proportion of registered students that spend more than 20 minutes to get to school.
X = 13 represent the number of students in the sample selected that have a time more than 20 min.
And then the estimated proportion of interest would be:
And we want to check if we can use the normal approximation given by:
So in order to do this approximation we need to satisfy some conditions listed below:
1) We need a random sample. For this case we assume that the sample selected was obtained using the simple random sampling method.
2) We need to satisfy the following inequalities:
So then we satisfy this condition:
3) 10% condition. For this case we assume that the random sample selected n represent less than 10% of the population size N . And for this case we can assume this condition.
So then since all the conditions are satisfied we can conclude that we can apply the normal approximation given by:
So then the answer for this case would be:
a. Yes.
