Answer:
The treatment should be stated by the four companies,since it more interested in the quality among each of the companies to be compared.
Step-by-step explanation:
From the example given, Since an electronic company wants to differentiate their cell phones quality to the cell phones from their three main competitors.
If ANOVA is used to determine the average number of defects, then the treatment should be defined for the four companies because it is more interested in comparing the quality among the different companies.
The first step is 10 - 7 + (2)(14)/4 which equals (2-step) = 3 + 28/4 (3-step) = 3 + 7 (finale-step) = 10
Keeping in mind that, there are 12 months in a year, therefore, 7 months is really just 7/12 of a year.
So we know that:
2x+3x+4 =25 (this is what the description above says).
we can add the xs and substract 4 from each side.
7x=21.
divide both sides by 7:
x=3
and now the pieces:
first piece is 2x: 2*x=6.
second piece: 5*x=15 feet.
