Answer #1

The added component in a two-way analysis of variance is called the interaction effect.

Reason:- let A and B be two factors whose mean effects are given by . then because of these two factors an interaction effect is added and is denoted by . It is an effect peculiar to the combination (Ai,Bj). It is not present in the ith level of A or in the jth level of B if not taken together. If the joint effect of Ai and Bj is different from the sum of the effects due to Ai and Bj taken individually, we say that there is interaction and it is measured by .

Capiz Corporation uses the two-way overhead variance analysis. During the recently ended period, total controllable variance was determined to be at P16,000 unfavorable while total non-controllable variance was at P6,000 favorable. Total actual factory overhead amounted to P3,530,000. Actual production totaled 352,000 units while standard machine hours per unit produced is 2 hours. Total budgeted capacity is 700,000 machine hours. a. How much is the total overhead applied to actual production? b. What is the standard overhead rate per hour?...

agree or not? Question 1: what is a one-way analysis of variance used for (Section 12-2)? One-way ANOVA (Analysis of Variance), is a statistical test that compares the variance in the group means within a sample while considering only one independent variable or factor. The hypothesis based test that is aimed to evaluate multiple mutually exclusive theories about data. In a one-way ANOVA there will be two different hypotheses. Meaning a test is done with two groups to see whether...
