In a company where manufacturing overhead is applied based on machine hours, the predetermined allocation rate is $3 per machine
1 answer:
Answer:
The overhead is over allocated by $1000.
Step-by-step explanation:
The manufacturing overhead is applied based on machine hours, the predetermined allocation rate is $3 per machine hour.
Actual machine hours were 3,000 making the cost as = dollars
But the actual manufacturing overhead was $8,000.
So, the overhead is over allocated by = dollars
Therefore, the answer is over allocated by $1000.

Answer:
a) P(k≤11) = 0.021
b) P(k>23) = 0.213
c) P(11≤k≤23) = 0.777
P(11<k<23) = 0.699
d) P(15<k<25)=0.687
Step-by-step explanation:
a) What is the probability that the number of drivers will be at most 11?
We have to calculate P(k≤11)
b) What is the probability that the number of drivers will exceed 23?
We can write this as:
c) What is the probability that the number of drivers will be between 11 and 23, inclusive? What is the probability that the number of drivers will be strictly between 11 and 23?
Between 11 and 23 inclusive:
Between 11 and 23 exclusive:
d) What is the probability that the number of drivers will be within 2 standard deviations of the mean value?
The standard deviation is
Then, we have to calculate the probability of between 15 and 25 drivers approximately.
