0.084

Step-by-step explanation:

Formula to find standard error of $\hat{p}$ for finding confidence interval for p:

$SE=\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

, where $\hat{p}$ = sample proportion and n= sample size.

Let p be the population proportion of students named math as their favorite class.

As per given , we have

n= 32

$\hat{p}=\dfrac{21}{32}=0.65625$

Substitute these values in the formula, we get

$SE=\sqrt{\dfrac{0.65625(1-0.65625)}{32}}\\\\=\sqrt{0.00705}\\\\=0.0839642781187\approx0.084$

∴ The correct value for the standard error of $\hat{p}$ in this case = 0.084
