Assume that the population standard deviation is know to be 3.0 hours. At a=0.05, can you construct an average time interval spent by the current college student is differ from 14 hours?
Use the data evaluate aggregate production planning using different strategies (subcontracting, chase strategy, level scheduling,mixed strategy). Please send excel file.
A set of 10 data values has a mean and median of $1,425 and ranges from a minimum value of $987 to a maximum value of $1,945. Later, we discover that the $1,945 value was mis-recorded and should hav
