*For operations management statistics practice quiz-please just list the answers:
1) A production process has six subsequent stages, each with their own specific resources and performing crucial tasks. Four of these stages have a capacity of 20 units per hour, while the other two stages have a capacity of 10 units per hour. What is the best conclusion?
The two stages with a capacity of 10 units per hour should be eliminated from the process.
Both stages with a capacity of 10 units per hour can be considered bottlenecks.
The four stages with a capacity of 20 units per hour can be considered bottlenecks.
There are no bottlenecks in this production process.
2) A production process has six stages, each with their own specific resources. If the stage with the lowest capacity (i.e., the bottleneck) has a capacity of 10 units per hour, then:
The production process has a capacity of 10 units per hour
The production process has a capacity of less than 10 units per hour
The production process has a capacity of more than 10 units per hour
The production process can have any capacity, depending on the other stages
3) KiNE's days that payments are outstanding are 40, their days that sales are outstanding are 50, and their cash conversion cycle is 60 days. How long do items spend in inventory at KiNE's? Assume a year has 360 days
60 days
210 days
40 days
50 days
4) At Amsterdam's Glue-Less coffee joint, you wait, then you are seated at a table, then you leave. The wares are so cheap that on average a person has to wait 20 minutes before getting a table. On average there are 12 people waiting and 24 customers actually at tables. How long does a person spend, on average, at a table (not including waiting)?
30 minutes
60 minutes
15 minutes
40 minutes
5) To properly analyze a Little's Law problem, you should:
Identify the number of stages in the supply chain.
Always remember that it only applies to manufacturing companies.
Draw a picture, draw a picture, PLEASE draw a picture!
Be familiar with really advanced mathematics.
6) A local grocery store has five cashiers that can each help a customer in, on average, 5 minutes. On average, 120 customers arrive at the grocery store per hour. What is the (implied) utilization for each cashier?
200%
50%
120%
100%
7) If the arrival rate equals 12/hr, then
The processing time is on average 12 minutes
The average interarrival time equals 5 minutes
The utilization is 8% (i.e., 100% / 12)
The capacity of that resource is also 12/hr

A survey was given with 125 respondents about raising minimum wage. Results are shown in a two way table below.
| for raising | against raising | no opinion | total | |
| age 21-40 | 35 | 20 | 5 | 60 |
| age 41-50 | 30 | 35 | 20 | 85 |
| total | 45 | 55 | 35 | 145 |
i) What is the probavility the respondent is of age 21-40, and has no opion?
ii) Given that a respondent is of age 21-40, what is the probability the respondent is against raising the minimum wage?
iv) Are the events 'For raising minimum wage' and 'aged 21-40' independent? Support your answer with a calculation

Python:
def factors(matrix, factor):
The matrix is a 3D list of integers.
factors are either one, two, or three
If the factor is 'one' it will return a the first value from each list
if the factor is 'two' it will return the second value, and same for the third.
Example;
input = [ [ [1, 2, 3], [3, 2, 9], [9, 8, 6] ],
[ [0, 0, 4], [8, 9, 0], [5, 2, 1] ],
[ [0, 1, 1], [5, 5, 9], [3, 8, 4] ] ], 'one')
output = [ [1, 3, 9], [0, 8, 5], [0, 5, 3] ]
