Attachment I:
a) From the regression line we find that slope is 0.81 for tch experience This means for 1 unit score to be increased for math score we have to increase 10 times the slope.
Hence for I model Tch experience to be increased = 10/0.81 = 12.346 years.
This is because we got linear co
elation and slope expresses the increase in mathscore for unit increase in tch experience.
) No, there cannot be diminishing returns as slope i.e. rate of change is constant in linear equal to 0.81
c) In the log linear model slope of ln (TCHExper) is positive and hence being linear relationship slope is positive and constant. This indicates ln Mathscore vs tchexper graph shows a constant rate.
i.e. rate of change of Matchscore = 5.63 (ln tchexperience)
Slope for teaching...
