The following table shows the number of females in a country in 2000, broken down by age. Numbers are in millions. Age 0–18 18–25 25–35 35–45 45–55 55–65 65–75 75 and over Number 34.5 14.8 19.8 23.9 19.4 12.6 10.3 10.5 Construct the associated probability distribution (with probabilities rounded to four decimal places). Age 0–18 18–25 25–35 35–45 45–55 55–65 65–75 75 and over Probability Use the distribution to compute the following. (Round your answers to four decimal places.) (a) P(18 ≤ X ≤ 55) (b) P(X ≤ 45) (c) P(X ≥ 45) Please fill in the blanks and complete a, b, and
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.
