Step 1 From the provided information, Sample size (n)=1830 Male (x)=1031 Level of significance (α)=0.01 Step 2 The hypotheses can be constructed as: H0:p=0.5 H1:p&amp;gt;0.5 Sample proportion (p―)=10311830=0.5634 Step 3 The value of the test statistic can be obtained as: z=p―−pp(1−p)n =0.5634−0.50.5(1−0.5)1830 =5.4243 Thus, the test statistic is 5.4243. Step 4 The p value of the test statistic from the standard normal table is 0.00001 which is less than level of significance, therefore, the null hypothesis would reject and it can be concluded that there is sufficient evidence to support the claim there are more male children dying of poisoning than female children.
