36 - The lifetime of the phones produced in factory A is 2900 days. The phones produced in factory B have a lifespan of 2600 days. A sample of 50 telephones was taken from factories A and B. Since the standard error of the difference between the sample averages of the phone lifetimes is 25.49, what is the probability that the mean of the sample from factory A will be more than 325 days from the mean of the sample from factory B? A) 0.483
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.
