Berkeley College students have been surveyed to determine if they prefer to work in groups or individually for projects. There are 4 students who prefer to work in groups for every 5 students who prefer to work individually. If there were 2,200 students who prefer to work in groups, how many students were surveyed in total?
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.
Question4: Berkeley College students have been surveyed to determine if they prefer to work in groups or individually for projects. There are 4 students who prefer to work in groups for every 5 students who prefer to work individually. If there were 2,200 students who prefer to work in groups, how many students were surveyed in total?
Question 5: Each year an organization raises money to offer Berkeley College students scholarships. They currently have raised $14,300. This represents 65% of the money they raise. Determine the amount of money the organization will raise in total.
Question 6: The frequency distribution below indicates the scores of 30 students who took the final exam for Math CSK 85 last semester.
a) Construct the relative frequency table for the data.
