Q: A UD coop performed a time study of an operation and recorded the following average cycle times:
.120, .147, .156, .131, .122, .140, .155, .136, .144, .125
The coop said that his supervisor wanted to be 95% confident that the mean of the samples was within plusminus 5% of the population mean. The coop asked you if this was enough cycles to study to satisfy his supervisor or if more samples are needed. Calculate the number of cycles and answer the coop's question.
