The regression line for a data set giving sales S, in dollars, t years after 2016 is S = 230t + 2200. (a) Explain in practical terms the meaning of the slope. The slope of 2200 dollars per year means that sales for the pertinent period are decreasing by $2200 each year. O The slope of 2200 dollars per year means that sales for the pertinent period are increasing by $2200 each year. O The slope of 230 dollars per year means that sales for the pertinent period are decreasing by $230 each year. O The slope of 2200 dollars means the initial sales are 2200 dollars in 2016. O The slope of 230 dollars per year means that sales for the pertinent period are increasing by $230 each year. (b) What sales are indicated for 2019?

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.
