# Time Study and Work Sampling – Working Analysis (Industrial Engineering)

ISYE 310 – Work Sampling Lab
Flip four coins and flip them all at once (this is a single measurement).Use something like https://www.random.org/coins/ ,Actual coins are too noisy and distracting
Repeat the flips for a total of 10.Record the number of heads (0 through 4) and plot.
Repeat 1 and 2 above a total of 10 times. This should give you a total of 100 flips. Plot the resulting 100 flips on one graph (as though they were one sample).
Compare the 10 separate distributions to one another and then compare to the larger single distribution.
Comment on the differences in the distributions and the similarity of the larger distribution to the normal.
For each of the 10 sets of distributions (treating each set as a separate measurement set), calculate percentage of times 1 or fewer heads appears).Use this value (e.g., about 31% over the long run? Ask yourself if and why this is correct?) as your estimated p value.
Calculate the number of observations needed to be 95% confident that the true probability is within plus/minus 2 points of the estimated value.
If you could only take 1000 observations, how confident would you be at the same limit of error?
If you could only take 1000 observations and needed to be 95% confident, what would be the resulting limit of error and range of values?
Submit data, graphs, and answers to all questions by next week.

## Industrial Fire Safety

Please make the 3 tasks on a single document. look at the World Microsoft file for more file about the assignment
Begin by reading through NFPA 652, NFPA 654, and NFPA 664. Summarize in a few paragraphs the purpose and basic outline of what these standards do. Write up your summaries in such a way for inclusion in your final report as if you had to explain the purpose of the code to non-technical business decision makers.
Identify the fire and dust explosion hazards in the process. This is where creativity and the NFPA standards (Hint: there are examples in NFPA 652) can guide you. Think about the different portions of the systems and where something can go wrong. For example, in the wood cutting machine, there exists a possible dust explosion hazard as the dust continues to build up. Additionally, if there is a steady stream of wood going into the machine, where is it coming from? Where is the wood stored, and are there means to ignite this fuel load? As another example to think about, how is power provided in these settings? Etc.

Analyze the hazards you develop in the context of the expected severity if the hazard occurs versus the probability of the hazard occurring. For this Task, develop a risk matrix following the definitions outlined in the risk matrix PDF, which is based on a Department of Defense document, MIL-STD-882E 2012 SYSTEM SAFETY for assigning risk in the military (refer to the one page Risk Matrix PDF). To build the matrix for your report, do the following for each hazard you identify:
