    sir, why didnt you multiply the r by 1000 like we did in regression??
    we should do that know?
  2. John MoffatTutor
    Because the top and bottom of the equation would both be multiplied by the same amount. So the result would not be affected.

    Hello Sir. Thank you so very much for the lecture, it helped me a lot in understanding the topic. I just had a doubt about the z score, will I be provided with the table for z score, discount and annuity in the exam? If yes then will it be a hard copy or will the question have it? and what are the tables or formulae sheets will I be given during the exam?
    Thank you for your response in advance.

    Coefficien of dertermination underroot of .98 should positive .98 and not .96 . is this correct?
  11. John MoffatTutor
    The coefficient of determination is the square of the coefficient of correlation.

    The coefficient of correlation is 0.98, and therefore the coefficient of determination is 0.98^2 = 0.96.
