4.You are an inmate in a prison and you have been found guilty of manufacturing weapons by the prison disciplinary board.The standard penalty for this offense is administrative segregation, aka, "The Hole."The number of days in segregation can be decided either by the prison disciplinary board or by the warden.You can choose who you want to determine your punishment.You decide to use statistics to help you make a decision.For two cartons of smokes and three cans of tuna fish, you are able to get sentencing data for the past 5 years.
Here are the results: The warden gives an average of 115 days segregation with a standard deviation of 20 days.
The disciplinary board gives an average of 100 days of segregation with a standard deviation of 5 days.
Using the standard deviation and the Empirical Rule, determine who will you choose to decide your punishment?Explain.(10)
