Aregression model between sales (y in $1000s), unit price (x1 in dollars) and television advertisement (x2 in dollars) resulted in the following function: ŷ = 7-3x1 + 5x2 for this model, ssr = 3500, sse = 1500, and the sample size is 18. if we want to test for the significance of the regression model, the critical value of fat 95% confidence is
a. 3.29
b. 3.24
c. 3.68
d. 4.54

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
