We need to find the correct option for the given data.

We know that

The null hypothesis asserts that the variables are unrelated, whereas the alternative hypothesis asserts that they are.

$H_0:p_1=0.55,p_2=0.30,p_3=0.08,p_4=0.07$

$H_{伪}$represents that at least one $p_i$is incorrect

And expected frequencies are a product of row and column total divided by table total.

And The squared differences between the actual and predicted frequencies, divided by the expected frequency, make up the chi-square subtotals.

White: ${蠂}^2=1.8889$

Black: ${蠂}^2=1.3009$

Hispanic: ${蠂}^2=3.2049$

Other: ${蠂}^2=0.1785$

We can see that the Hispanic group has the highest chi-square subtotal, and hence the Hispanic category contributes the most to the statistic. Furthermore, the observed count ($18$) is $6.16$times higher than the projected count ($11.84$).

Therefore,

Correct option is (d).
