At 0.10 level of significance, analyze the data shown using a two-way ANOVA. Building Type (B) Subcontractor (A) 25 30 20 28 32 30 C1 26 35 32 30 29 29 31 31 28 35 31 33 28 37 25 C2 32 28 24 31 25 37 27 29 33 1. Perform two-way ANOVA using excel 2. Complete the table below.

Type A if "there is no difference in the means" Type B if "at least one mean is different from the others" Type C if "they are dependent" Type D if "they are independent" 4. What is the null hypothesis for the building type? Type A if "there is no difference in the means" Type B if "at least one mean is different from the others" Type C if "they are dependent" Type D if "they are independent" 5. What is the null hypothesis for the interaction? Type A if "there is no difference in the means" Type B if "at least one mean is different from the others" Type C if "they are dependent" Type D if "they are independent" 6. What is the decision for the subcontractor? Type ACCEPT if you should accept the null hypothesis Type REJECT if you should reject the null hypothesis 7. What is the decision for the building type? Type ACCEPT if you should accept the null hypothesis Type REJECT if you should reject the null hypothesis 8. What is the decision for the interaction?
