Mickey Ds Coffee division has been burned with recent lawsuits alleging their coffee was too hot, while at the same time facing numerous complaints their coffee served at their outlets was not hot enough. The Federal Board of Control of Coffee Temperature dictates lower and upper limits, respectively, of 170F and 200 F and Mickey Ds treats these limits as their Voice of the Customer data.

Mickey Ds has hired an MBA intern to perform Statistical Sampling at a few of their Triangle outlets. Here are the sample data from one particular outlet in F.

	Observation 1	Obs 2	Obs 3	Obs 4	Obs 5
Day 1	183	186	181	179	185
Day 2	186	177	190	179	174
Day 3	193	184	195	180	192
Day 4	181	195	193	194	181
Day 5	177	190	187	185	190
Day 6	175	184	182	187	187
Day 7	180	191	184	183	184
Day 8	180	180	184	177	172
Day 9	190	188	184	188	184
Day 10	186	185	188	186	185

1. Based on the sample of observations, what is the probability of the temperatures falling outside either limit as set by the Federal Board of Control of Coffee Temperature?

Probability of Violating Limits = %
