Explanation:
Primary data are data collected or retrieved from the source. These data are obtained directly by researchers from the source where the data emanate from. Examples of primary data are survey, interview, group discussion.
Secondary data are data collected by other people other than the source or user. Examples are reports, news paper articles, journals etc.
Most international researchers collects their own primary data because of the difficulty and scarcity of collecting reliable secondary data. Both types of data are important though but the difficulties in obtaining those reliable secondary data prompts the collection of primary data.
These researchers goes to the root or source of the data to be collected because their findings will eventually be relied upon by users like individuals, government, corporate organizations, schools etc. Relying on secondary data might be hard because they might have be tampered with or altered which may not reflect the true nature of the data.
Answer:
cost of goods manufactured= $490,000
Explanation:
<u>To calculate the cost of goods manufactured, we need to use the following formula:</u>
cost of goods manufactured= beginning WIP + direct materials + direct labor + allocated manufacturing overhead - Ending WIP
cost of goods manufactured= 20,000 + 120,000 + 190,000 + 170,000 - 10,000
cost of goods manufactured= $490,000
Answer: (a ) 4 per hour (b ) 4.5 minutes (c ) 3 minutes
Explanation:
Average time between customer arrival = 15 minutes
Average service time = 10 minutes
(a) To calculate the customer arrival rate
Arrival rate = 1 / time between Arrival
= 1 / 15
= 0.066 × 60
= 4 per hour
(b) To calculate the average number of customers in queue
( Arrival time )^2 / service time ( service time - Arrival time)
= (15)^2 / 10 ( 10 - 15)
= 225 / 10 (-5)
= 225 / 50
= 4.5 minutes
(c) To calculate the average time customers spend in the system
Arrival time / service time - Arrival time
= 15 / 10 - 15
= 15/ -5
= 3 minutes
