Guy Said:

is there any professional institute who charge money and solves the case study for candidate?

We Answered:

Yeah - they are called LAW FIRMS. Rather expensive too.

Andrea Said:

which Indian Author you refer for Indian Contract Act 1872 and Case law for students of professional studies? ?

We Answered:

N D Kapoor.
H K Saharay ( Publisher: Eastern Law House)

A website called NET LAWMAN also gives productive insights on Indian Contract Act.

All the best for you CA Exams!

AP STATS CASE STUDY: CHPT 7. URGENT!!!?

We Answered:

1. The random variable of interest is Baylock's adjusted score. For brevity, let's agree to call the random variable S.

2. Yes, because the model has the following two properties:

(i) 0 <= P(S = s) <= 1 for all possible values of s, i.e, 210, 213 (all the probabilities are between 0 and 1)
(ii) P(S = 210) + P(S = 213) + . . . + P(S = 231) = 1 (all the probabilities sum to 1)

3. E[S] = 210*.07 + 213*.16 + . . . + 231*.01 = 218.16

4. VAR[S] = E[S^2] - E[S]^2 = 21.4344
STD[S] = sqrt[VAR[S]] = 4.62973

Note: E[S^2] = 210^2*.07 + 213^2*.16 + . . . + 231^2*.01 = 47593.7856

5. P( S <= 218 ) = .07 + .16 + .23 = .46

P( S <= 220 ) = .07 + .16 + .23 + .24 = .70

P( 209 <= S <= 218) = .07 + .16 + .23 = .46

Question 5 is somewhat confusing. Although in reality Baylock could get a score of 218, the random variable S would take the value 219. In this question, we're being asked to find probabilities involving the random variable assigned to Blaylock's actual score. The questions would be clearer if they were reworded with "Baylock's adjusted score" in place of "Baylock's score". (We do not have enough information to find the probabilities involving the actual scores. This particular model, as noted by the author/authors is a simplification of the actual situation. Therefore, we expect that although our answers will be meaningful, they will not be as accurate as they could be.)
