**Hint:** You need to perform a test for equality of sample proportions from two independent populations. The test statistic for testing the difference in two population proportions, that is, for testing the null hypothesis $$H_0:p_1−p_2=0$$ is:
$$Z=\dfrac{(\hat{p}_1−\hat{p}_2)−0}{\sqrt{\hat{p}(1−\hat{p})\left(\dfrac{1}{n_1}+\dfrac{1}{n_2}\right)}} \sim N(0,1)$$
where: $\hat{p}=\dfrac{Y_1+Y_2}{n_1+n_2}$ is the proportion of "successes" in the two samples combined. In your case
* $n_1=n_2=11000$ and
* $Y_1=104, Y_2=189$.
You only need to specify the significance level $α$ at which you will perform the test. If not given by the exercise you can choose $α=5%$ or $α=1%$.
