Chapter 15, Problem 34CP

Multiple choice Nonparametric statistical methods are used

  1. a. Whenever the response variable is known to have a normal distribution.
  2. b. Whenever the assumptions for a parametric method are not perfectly satisfied.
  3. c. When the data are ranks for the subjects rather than quantitative measurements or when it’s inappropriate to assume normality and the ordinary statistical method is not robust when the normal assumption is violated.
  4. d. Whenever we want to compare two methods for getting a good tan.

A well-known company predominantly makes flat pack furniture for students. Variability with the automated machinery means the wood components are cut with a standard deviation in length of 0.45 mm. After they are cut the components are measured. If their length is more than 1.2 mm from the required length, the components are rejected. a) Calculate the percentage of components that get rejected. b) In a manufacturing run of 1000 units, how many are expected to be rejected? c) The company wishes to install more accurate equipment in order to reduce the rejection rate by one-half, using the same ±1.2mm rejection criterion. Calculate the maximum acceptable standard deviation of the new process.
5. Let X and Y be independent random variables and let the superscripts denote symmetrization (recall Sect. 3.6). Show that (X + Y) X+ys.
8. Suppose that the moments of the random variable X are constant, that is, suppose that EX" =c for all n ≥ 1, for some constant c. Find the distribution of X.
