#' @title Judgment samples of plastic blocks
#'
#' @description 
#' 
#' Thirty-three graduate students were shown a set of 100 "physical blocks" of different shapes and sizes, all cut from a single sheet of opaque plastic a few millimetres thick (see  \code{\link{blocks}}).
#' 
#' The blocks were numbered 1 to 100 and each student was asked to choose 10 blocks whose average weight would, in their judgment,  equal the average weight of all 100 blocks.
#' The only information available to each student to help them make their choice was the visual shape and size of all 100 blocks.
#' They had a few minutes each to make and record their choices.
#'  
#' The task was presented as a competition with a prize to go to the student whose sample came closest to the population average weight.
#' 
#' Actual block weights and other information are available in the dataset \code{\link{blocks}}.
