#' Tukey Quantile Table
#' 
#' Builds a table with quantiles of the sample relative range distribution.
#' 
#' 
#' @param alpha The probability of type-I error of false alarm , that is equal
#' to 1 minus the confidence level.
#' @param n The maximum sample size.
#' @return It is used the fact that the sample relative range distribution is
#' the same as the sample studentized range distribution (tukey distribution)
#' with infinity d.f. in the denominator . It is considered 4 quantiles:
#' alpha/2 , alpha , 1-alpha and 1-alpha/2, for different sample size values .
