Then we say that Y has a log normal distribution. (a) Why do we use the name “log-normal”? (b) Find an expression for fY (t). (c) Sketch the graph of fY . (11) Let X ∼ N (0, 1). 3413. Verify this using numerical integration. (12) Buffon’s needle. Suppose that a plane is ruled by equidistant parallel lines at distance 1 apart: for example represent the lines by y = n(n = 0, ±1, ±2, ±3, . ). A needle of length L < 1 is thrown randomly on the plane. (a) Prove that the probability that the needle will intersect one of the parallel lines is 2L/π.
B) Carefully describe a practical situation which would give rise to a random variable whose distribution you would expect to be a Normal distribution. State some sensible values of the parameters µ and σ involved. (c) Carefully describe a practical situation which would give rise to a random variable whose distribution you would expect to be a non-symmetric or skewed distribution. (5) In many elementary statistics books, we find a statement of the socalled “empirical rule”. 95. The aim of this exercise is to examine the limitations of this “rule”.
