#' STAT210prob2.32: Effect of Cool-Down Time on Cell Phone Housings
#'
#' This data contains results from an experiment on the cool-down time for
#' the moulding process of front housings for cell phones. The experiment was
#' conducted using two cool-down times, 10 and 20 seconds. 20 housings were
#' evaluated at each level of cool-down time. All 40 observations in this
#' experiment were run in random order.

#' @details
#'
#' Front housings for cell phones are manufactured in an injection moulding
#' process. The time the part is allowed to cool in the mould before removal is
#' thought to influence the occurrence of a particularly troublesome cosmetic
#' defect, flow lines, in the finished housing. After manufacturing, the
#' housings are inspected visually and assigned a score between 1 and 10 based
#' on their appearance, with 10 corresponding to a perfect part and 1
#' corresponding to a completely defective part.
