5. For each of the following, state whether the statement is true or false and justify your answer. a) If a distribution is skewed, it's better to give the median and IQR instead of the mean and standard deviation. b) A man is in the 96th percentile for blood pressure in his age group. This means his blood pressure is better than 96% of those in his age group. c) Two variables X and Y have a correlation of 0. This means the two have no relationship. d) For a continuous random variable X, P(X < x) = P(X < x). e) The main benefit of an observational study is we can determine causation between two variables. f) Let X be the time until a car arrives at a stop sign. Then we can model X as X * Ga(r,2) for some r and 1.
