Suppose that customer interarrival times are exponentially distributed with mean 8 customers per hour. To simulate customer interarrival times in MS Excel in minutes, one would use: O =-In(1-RAND())/8 O =-In(1-RAND())*7.5 O =EXPON.INV(RAND(),8)*60 O =NORM.INV(RAND(),7.5,7.5) O Exactly two answers are correct. O None of the answers are correct
