The American Court Reporter Institute finds that the average student taking Elementary Machine Shorthand will progress at a rate given by dQ = k(80 – Q) dt in a 20-week course, where Q(t) measures the number of words of dictation a student can take per minute after t weeks in the course. If the average student can take 50 words of dictation per minute after 9 weeks in the course, how many words per minute can the average student take after completing the course. (Assume the student initially takes 0 words per minute.) Round your answer to the nearest word.

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.
