Months between occurrences of safety violations

Reference no: EM131002665

The table below shows the time in months between occurrences of safety violations for three operators, "A," "B," and "C," working in a toll manufacturing facility.

A	1.31	0.15	3.02	3.17	4.84	0.71	0.70	1.41	2.68	0.68
B	1.94	3.21	2.91	1.66	1.51	0.30	0.05	1.62	6.75	1.29
C	0.79	1.22	0.65	3.90	0.18	0.57	7.26	0.43	0.96	3.76

Postulate an appropriate probability model for the phenomenon in question, treat the data set as three random samples of size n = 10 each, from the three different populations represented by each operator. Obtain precise 95% con?dence interval estimates of the unknown population parameters. Interpret your results in terms of any differences that might exist between the safety performances of the three operators.
