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.

Question

Weights of Vacuum Cleaners Upright vacuum cleaners have either a hard
body type or a soft body type. Shown are the weights in pounds of a sample of
each type. At a=0.05, can it be concluded that the means of the weights are
different? Assume the variables are normally distributed and the variances are
unequal.
