Suppose a researcher surveyed the general public in two countries, asking the question "Do you think that we already started observing the negative impacts of global warming?". The below table summarizes the answers. Test at 5% significance level that the share of "significantly" answer is statistically significantly different in these countries. Enter your answer as the critical value calculated, with 2 digits after the decimal point after rounding the 3rd digit (e.g. 2.34567 = 2.35).
