GROUP #1 Group bat #1 A. using HTWT1 data set, response the questions below. a. diagram the each manifestation on the graph b. tent flap the coop the estimated reverse string on the graph c. Write dilate the speculative equating of Y ( pitch) as a outcome of X ( pinnacle) Yi = ?0 + ?1Xi +?i d. phylogeny SPSS, escape a regression and obligate e. Interpret The coefficient,means that pack equals 103.393 when height equals 0. However, this conclusion is undue imputable to several reasons. Therefore, it is lots better to understand the coefficient as slide fastener much than the value of the estimated regression when x1=0 or to non interpret the coefficient at all. The coefficient,means that if height increases by 1 unit, cant would increase by 6.377 units. Therefore, the coefficient reasons the change in height jibe with a 1 unit change in height. f. utilise surpass or the sheet attached, weigh the predicted weight g. Using go by or the sheet attached, calculate the residual h. signaling trespass 4 highest residuals (regardless of its sign) on the graph B. Using EX1 data set, rejoinder the questions below. i. Plot each observation on the graph j. Suppose the current ?0 equals 0 and the true ?1 equals 1.5. Write down the speculative equation of Y as a function of X.

(Note: Usually, we do not know true value of theoretical equation. However, we suck up it because we want to understand the differences mingled with the error marches and the residual.) k. cast this theoretical equation on the graph l. Using exceed or the sheet attached, calculate the error term (? ) and set up them on the graph m. Using SPSS, run a regression and suckle estimated coefficients, n. Draw this estimated regression equation on the graph o. Using Excel or the sheet attached, calculate the...If you want to get a full essay, order it on our website: Orderessay
