Question

You work at a manufacturing company that

makes car seats. There are seven manufacturing plants in the US, and

your boss has asked you to assess time efficiency in

current production lines. Your boss has no idea how long or short the manufacturing

process takes or how variable the process may be. Create a data collection plan and

describe what data you would present to your boss. This is an open ended question, and

there are many correct answers. Go through the process of:

a) defining your population,

b) defining how you would take a random sample (how will you collect data comprehensively?)

c) describing the sample data

D) describing techniques you may use to visualize your data.

Answer 1

a)

The efficiency times in current production lines of all seven manufacturing plants of car seats in the US.

b)

I would collect the efficiency times of recent week from each of the seven manufacturing plants. If there are any time and cost constraints, then I would pick at least 3 plants randomly to collect the sample.

c)

The sample data contains efficiency times of at least 3 plants for the recent week and the measures of central tendency such as mean and the measures of dispersion such as standard deviation for the sample of efficiency times are calculated.

d)

There are various techniques that can be used to visualize the data such as Frequency table, Histogram, Box plot, etc,. that would help us to see the type of distribution and find any outliers so that they can be removed before proceeding with calculations of central tendency (such as mean) and dispersion (such as std.deviation) which are further used in statistical tests (if any or if we want to).
