Question

Refer to the data below which contains the percentage change (X) in a stock market index over the first five trading days of the year and percentage change (Y) in the index over the whole year. Complete parts a and b. (X) 1.4 0.4 -0.2 2.8 2.4 -1.9 -1.5 5.6 -1.6 1.3 1.7 -4.7 0.8 (Y) 14.9 -9.1 19.7 20.1 -3.6 27.7 22.5 2.3 11.8 28 -4.4 20.4 -0.8 a. Estimate the linear regression of Y on X. ?i = + ( )xi (Round to four decimal places as needed.) b. Provide interpretations of the intercept and slope of the sample regression line. For a one percent over the first five trading days of the year, estimates would predict a change of % over the whole year. If there is a zero percent change over the first five trading days of the year, estimates would predict a change of % over the whole year.
