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)	1.6	0.2	0.2	2.7	2.2	1.7	1.6	5.6	1.3	1.4	1.5	4.7	0.5
(Y)	14.9	9.4	19.7	20.1	3.6	27.7	22.7	2.2	11.8	26	4.1	20.3	0.1

a. Estimate the linear regression of Y on X.

yi=_______+_______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 (gain/loss) over the first five trading days of the year, estimates would predict a change of (1.8837/ 11.411.4/ 12.1535/ 0.4/ 0/ 0.3754) % 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

(1.8837/ 12.1535/ 0.4/ 11.4/ 0.3754/ 0) % over the whole year.
