The 2012 National Vital Statistics Report provides information on how the nearly four million live births that occurred in 2010 broke down by birth order. Choose at random a baby born in America in 2010: Birth Order 1 2 3 4 5 6 7 Probability 0.38 ______ 0.19 0.11 0.04 0.02 0.01
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.
The 2012 National Vital Statistics Report provides information on how the nearly four million live births that occurred in 2010 broke down by birth order. Choose at random a baby born in America in 2010:
| Birth Order | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
| Probability | 0.38 | ______ | 0.19 | 0.11 | 0.04 | 0.02 | 0.01 |
a) Describe the
b) Write the event “a woman gives birth in 2010 to her 3rd or more child” in terms of values of X.
c) What is the probability of the event in #13d, above?
Given Information:
The 2012 National Vital Statistics Report provides information on how the nearly four million live births that occurred in 2010 broke down by birth order.
| Birth Order | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
| Probability | 0.38 | 0.19 | 0.11 | 0.04 | 0.02 | 0.01 |
Sum of probabilities for a probability distribution is 1. Missing value is obtained as follows:
Thus, P(X = 2) is 0.25
