χ2=(1027.56)227.56+(4224.44)224.44+(425.44)225.44+(522.56)222.56=55.54\chi^2=\frac{(10-27.56)^2}{27.56}+\frac{(42-24.44)^2}{24.44}\\+\frac{(4-25.44)^2}{25.44}+\frac{(5-22.56)^2}{22.56}=55.54

Critical value:

χ2(1,0.05)=3.84\chi^2(1,0.05)= 3.84

Test statistic is greater than critical value. Thus, we can conclude that there is a relationship between hypertension and obesity in the males and females

separately, under the given study at 0.05 level of significance.
