A random variable X is said to follow a lognormal distribution if Y = log(X) follows a normal distribution. The lognormal is sometimes used as a model for heavy-tailed skewed distributions. please answer the follow: 110 15 60 5419 15 73 190 57 4344 18 37 43 55 19 23 82 175 50 80 65 63 36 6 10 17 52 43 70 22 95 20 4 17 15 12 29 29 6 22 40 17 26 30 16 116...
