Question:

The accompanying data resulted from a flammability study in which specimens of five different fabrics were tested to determine burn times.

MSTr = 23.67 MSE = 1.39 F = 17.08 P-value = .000 The accompanying output gives the T-K intervals as calculated by Minitab. Identify significant differences and give the underscoring pattern. Individual error rate = 0.00750 Critical value = 4.37 Intervals for (column level mean) - (row level mean)
