Use software to generate a multiple regression output for the given data:

x1x1	15	22	21	17	19	8	14	21	23	14	20
x2x2	11	7	6	8	7	14	9	9	7	14	9
x3x3	3	3	12	6	6	10	3	12	11	10	8
yy	89	144	165	118	136	73	108	114	139	69	108

a. Develop the multiple regression equation for estimating yy based on x1x1, x2x2, and x3x3.

y^=y^=

++

x1+x1+

x2+x2+

x3x3Round to three decimal places

b. Interpret the value of b2 in the equation. For each 1 unit increase in x2x2, yy
