ROI as a financial ratio is calculated as follows:
ROI = Net profit/Total investments
In the current case,
Net profit = Net operating income = $700,000
Total investments = Operating assets = $600,000
After purchasing the new machine,
Total investments = 600,000*1.08 = $648,000
Therefore, the new ROI is;
ROI = 700,000/648,000 ≈ 1.08 = 108%
Answer:
D. SST is the total sum of squares. It represents the total variation among all the sample data.
Explanation:
Analysis of variance (ANOVA) "is used to analyze the differences among group means in a sample".
The sum of squares "is the sum of the square of variation, where variation is defined as the spread between each individual value and the grand mean"
If we assume that we have groups and on each group from we have individuals on each group we can define the following formulas of variation:
And we have this property
If we analyze SST compares the individual values respect the grand mean in order to find the total variation. so the best option for this case is:
D. SST is the total sum of squares. It represents the total variation among all the sample data.
