True and false problemI need your help

(h) The LIFT in the Association Analysis can be smaller than one. (i) In conducting a cluster analysis, we do not need to define a Target variable.~ (i) By default, the CCC value is 3, and it must be set at CCC = 3 for any cluster analysis. ( K) The weight estimates in the neural network modeling have the following interpretation: The large the weight (in magnitude), the more important the variable is to explain the target.~ (1 In a neural network modeling, if the target is binary, then, the activation function for the target layer must be Logistic activation. (m) Neural network modeling technique perform better when the data contains a lot of noise than when the data contains strong signal.
