A) $\hat { p } = 0.29 , \hat { q } = 0.29$
B) $\hat { p } = 0.71 , \hat { q } = 0.29$
C) $\hat { p } = 0.29 , \hat { q } = 0.71$
D) $\hat { p } = 0.71 , \hat { q } = 0.71$

$\hat { p }$ is the proportion of new cars that are white, which is 29 out of 100, or 0.29. $\hat { q }$ is the proportion of new cars that are not white, which is 1 - $\hat { p }$ = 0.71.
