A random variable X is said to follow a lognormal distribution if Y = log(X) follows a %3D normal distribution. The lognormal is sometimes used as a model for heavy-tailed skewed distributions. a) Calculate the density function of the lognormal distribution. b) Examine whether the lognormal roughly fits the following data (Robson 1929), which are the dorsal lengths in millimeters of taxonomically distinct octopods. (Using R) data <- c(110,15,60,54,19,115,73,190,57,43,44,18,37,43,55,19,23,82,175,50,80,65,63, 36,16,10,17,52,43,70,22,95,20,41,17,15,12,11,29,29,61,22,40,17,26,30,16,

I got an answer from an expert to the following question: Let X and Y be independent random variables with standard normal distribution. Calculate the distribution and density functions of X/Y. Instructions: use the distribution of arg(X,Y). He claims that the distribution of X/Y should be normal with mean 0 and variance 1, but the ratio of two independent normal distributions should give a Cauchy distribution. Or am I wrong?
