1. As part of a statistics project, a teacher brings a bag of marbles containing 700 white marbles and 400 red marbles. She tells the students the bag contains 1100 total marbles, and asks her students to determine how many red marbles are in the bag without counting them. A student randomly draws 200 marbles from the bag. Of the 200 marbles, 69 are red. A) The data collection method can best be described as • Controlled study • Census • Survey • Clinical study B) The target population consists of • The 1100 marbles in the bag • The 69 red marbles drawn by the student • The 200 marbles drawn by the student • The 400 red marbles in the bag • None of the above C) The sample consists of • The 69 red marbles drawn by the student • The 1100 marbles in the bag • The 200 marbles drawn by the student • The 400 red marbles in the bag • None of the above D) Based on the sample, how many red marbles would the student estimate are in the bag?

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.
