Answer:
(a) Given that a chip passes the test, what is the probability that it is a good chip?
LetB = {the chip is good}
A={the chip passes the cheap test}.
Bc={the chip is bad}
Ac={the chip fails the cheap test}
P(A | B) = 1
P(A | B c ) = 0.075
= =
≈ 0.9751
(b) If the company sells all chips that pass the cheaper test, what percentage of sold chips will be bad?
P(B c |A) = 1 − P(B | A) = 1 - 0.9751 = 0.0249
Answer:
If the Studio is the cost object, then all the costs that can be attributed to the studio itself will be direct and that includes all the costs except the <em>Planning and development materials sent from the home office, </em>because that comes from the home office not the studio in question.
As per the question, all the costs are also variable because there are different payment plans and the offers by the studio as well as materials needed are dependent on the number of students they have. Advertisements are a set price however and do not depend on the number of students and so are fixed .
If the Lessons were the cost objects, everything that cannot be linked directly to the lessons is an indirect cost. This includes all the costs excerpt the dancing instructors' salary as this is linked directly to the number of lessons they offer.
All costs will also be fixed because they are independent of the lessons offered and so are set amounts. The dancing instructors' salary is also fixed as the rates do not change in relation to lesson prices.
