如图，survivor和non-survivor两组之间性别比例的差异比较，可以用prop.test()函数么？如下：

> prop.test(c(15628,2407),c(28062,4489))

        2-sample test for equality of proportions with continuity correction

data:  c(15628, 2407) out of c(28062, 4489)
X-squared = 6.6343, df = 1, p-value = 0.01
alternative hypothesis: two.sided
95 percent confidence interval:
0.004877538 0.036542663
sample estimates:
   prop 1    prop 2
0.5569097 0.5361996
