1.The service time pattern of a single lane automated car wash service would most likely be exponential. True or False.

Answer = FALSE

  • service time pattern of a single lane automated car wash service would most likely be negative exponential probability distribution.

2.The value of the correlation coefficient "r" ranges between.

Answer = (D) -1 and +1

  • The closer r is to +1 or -1, the more closely the two variables are related
  • If r is close to 0, it means there is no relationship between the variables
