A study followed 20,000 pregnant women from conception. Among these women, 1,048 had miscarriages before 20 weeks gestation, an additional 356 had miscarriages before 28 weeks gestation, and another 112 had miscarriages after 28 weeks gestation. All remaining pregnant women had live births, however, 32 women died due to complications during labor and delivery. Among those live births, 18 babies died within 7 days of birth. Among the surviving infants, an additional 25 died prior to 28 days of age. And, following all surviving babies through their first year, another 43 infants died. What is the Infant Mortality Rate?
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
