3.2 A package delivery service divides their packages into weight classes. Suppose that packages in 14 to 20 pounds class are equally likely to occur. 3.2.1 provide a sketch diagram to summarise the above information. show precisely f(x), the mean value and the bounderies. 3.2.2 find the probability that a package weighs between 15 and 16.5 pounds. 3.2.3 find the probability that a package weighs less than 15 pounds 3.2.4 find the probabilirt that a package weighs at least 18 pounds. 3.2.5 Calculate the variance and standard deviation of the distribution.
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.
