The Tukey-Kramer post hoc test is not needed.Stop, the results were significant. The Tukey-Kramer post hoc test is not needed.    There is not enough information, so collect more data.Continue to the Tukey-Kramer post-hoc test, as the results were significant. (b) Suppose MSE = 127.5 and  k = 3.  What is the degrees of freedom for MSE? dfE = 3 − 1 = 2 dfE = 3(7) − 3 = 18      dfE = 3(7) − 1 = 20 (c) How many Tukey-Kramer comparison intervals need to be calculated?
