Y\u02c6=30+0.7X1+3X2<\/span><\/p>\n

Also provided are SST = 1,200 and SSE = 384.<\/span><\/p>\n

The yearly income of a 24-year-old male individual is?<\/span><\/p>\n

Y\u02c6=7\u22123X1+5X2<\/span><\/p>\n

For this model SSR = 3500, SSE = 1500, and the sample size is 18.<\/span><\/p>\n

The coefficient of the unit price indicates that if the unit price is<\/span><\/p>\n

a) increased by $1 (holding advertising constant), sales are expected to increase by $4,000<\/span><\/p>\n

b) increased by $1 (holding advertising constant), sales are expected to increase by $3<\/span><\/p>\n

C) increased by $1 (holding advertising constant), sales are expected to decrease by $3,000<\/span><\/p>\n

d) decreased by $1 (holding advertising constant), sales are expected to decrease by $3<\/span><\/p>\n
