Suppose you work in a textiles factory. You know that it's normal for machines to print an average 12 flaws per bolt of fabric. But if there's something wrong with the machine, they will print more flaws; you use this fact to determine if a machine needs to be fixed. Fixing a machine is always a time consuming process--it can require two hours just to take the machine apart to inspect it--so you only fix them if you really think there's something wrong. A machine just printed 15 flaws on a bolt of fabric. Using the appropriate distribution function in Excel, determine the chance that this is just a coincidence and the machine is working fine? Express your answer as a decimal to four places. Include a zero before the decimal point.

Transcribed Image Text:Suppose you work in a textiles factory. You know that it's normal for machines to print an average of 12 flaws per bolt of fabric.
But if there's something wrong with the machine, they will print more flaws; you use this fact to determine if a machine needs to
be fixed. Fixing a machine is always a time consuming process--it can require two hours just to take the machine apart to inspect
it--so you only fix them if you really think there's something wrong.
A machine just printed 15 flaws on a bolt of fabric. Using the appropriate distribution function in Excel, determine the chance that
this is just a coincidence and the machine is working fine? Express your answer as a decimal to four places. Include a zero
before the decimal point.
