Use the following information to answer the question. A researcher is studying the average number of messages sent by What's App users and iMessage users. Below is the R output produced from the data. > t.test(Whats_App, iMessage, alternative - "two.sided") Welch Two Sample t-test data: Whats_App and iMessage t - 0.52784, df - 13.775, p-value - 0.606 alternative hypothesis: true difference in means is not equal to 0 95 percent confidence interval: -23.02189 38.02189 sample estimates: mean of x mean of y 53.0 45.5 If the significance level is 1%, what conclusion can we make? We do not have enough evidence to conclude that the average number of messages sent by What's App users is less than iMessage users. We have enough evidence to conclude that the average number of messages sent by What's App users and iMessage users is different. We do not have enough evidence to conclude that the average number of messages sent by What's App users and iMessage users is different.

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.
