#' STAT210prob2.46: Equation for CI
#'
#' This is data for developing an equation for finding a 100(1 - \eqn{\alpha})
#' percent confidence interval on the difference in the
#' means of two normal distributions where \eqn{{\sigma_1}^2 != {\sigma_2}^2}.

#' This is data from Exercise 2.46 in Design and Analysis of Experiments, 9th
#' Edition, EMEA Edition. In this exercise you are suppose to apply the equation
#' to the Portland cement experiment data from example 2.1, and find a 95
#' percent confidence interval.
