    Sir, the question in the revision kit for this chapter..
    a) why is the answer : y = 32.84 – 0.0679x and not : y = 32.84 + 0.0679x? for i got a positive answer for b.

    Other than that. how do we know how many decimal places should we use in the exams as the b produces the answer of 0.067857142? Same goes to question c) as it results to 0.9554529 (95.5% in percentage) Please help. I’m very confused.
