The standard error (SE) of the sampling distribution difference between two proportions is given by:

SE=\sqrt{p(1-p)\left(\frac{1}{n_1}+\frac{1}{n_2}\right)}

where p is the pooled sample proportion, n_1<span> is the size of sample 1, and n_2<span> is the size of sample 2.

</span>p= \frac{p_1n_1+p_2n_2}{n_1+n_2}
<span>
Given that a</span><span>t one vehicle inspection station, 13 of 52 trucks and 11 of 88 cars failed the emissions test.

</span>p_1= \frac{13}{52} =0.25 \\  \\ p_2= \frac{11}{88} =0.125 \\  \\ n_1=52 \\  \\ n_2=88 \\  \\ p= \frac{0.25(52)+0.125(88)}{52+88}  \\  \\ = \frac{13+11}{140} = \frac{24}{140} =0.1714
<span>
</span>SE=\sqrt{0.1714(1-0.1714)\left(\frac{1}{52}+\frac{1}{88}\right)} \\  \\ = \sqrt{0.1714(0.8286)(0.0192+0.0114)}  \\  \\ = \sqrt{0.1714(0.8386)(0.0306)} = \sqrt{0.0044}  \\  \\ =0.0663<span>
