You find 6 statements below. Each statement is either true (T) or false (F) (write your choice in the table).  1) In a probability model, all possible outcomes together must have a probability of 1. 2) A density curve describes the probability distribution of a discrete random variable. 3) Outliers do not have a large effect when we calculate the mean. 4) The probability of success for binomial distribution must remain the same for each trail. 5) In the Normal distribution with mean μ and standard deviation σ, approximately 95% observations fall within ± 2σ of the mean μ. 6) Since the median is the middle value of a data set it must always be smaller than the mean.
