A fashion designer surveys companies about upcoming seasonal trends for average hem length. He surveys 3 major companies, comparing the average hem length of their proposed designs. From each company, he takes a random sample of 7 employees. The data are significant at ? = 0.05. (a) What is the next step in the one-way ANOVA? Stop, the results were not significant.

Question
A fashion designer surveys companies about upcoming seasonal trends for average hem length. He surveys 3 major companies, comparing the average hem length of their proposed designs. From each company, he takes a random sample of 7 employees. The data are significant at
? = 0.05.
(a)
What is the next step in the one-way ANOVA?
Stop, the results were not significant. 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?
