Example 156

Example 156: An experiment was conducted to determine if there is a difference between drying times for four different brands of outdoor paints.  A multiple comparison procedure was used to compare the different average drying times and produced the following intervals:

µA- µB   (3, 9)

µA- µC   (5, 7)

µA- µD   (-15, 4)

µB- µC   (-2, 8)

µB- µD   (-12, -5)

µC- µD   (-10, -4)
