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

Suppose Joe is seeking a job. He decides to
consider n possible jobs. However, after
being offered a job, he must immediately
decide whether to accept it or decline it and
consider the next job that becomes available
Notice that when considering a new job offer
Joe only knows the relative rank of that job
compared to the ones he has already
declined. Assume that all n! orderings are
equally likely and that once a job is declined i
is gone forever. Suppose Joe's strategy is to
reject the first k jobs and then accept the first
one that is better than all of those first k.
a For a given value of k, what is the
probability that Joe selects the best job?
b What value of k would maximize the
probability that Joe selects the best job
under this strategy?

Suppose that A E Mmxn(R) is a matrix of user ratings of various movies (on a scale of 1 to 5). Suppose we have computed the SVD of А, and decided to keep the 10 largest singular values as the most important determining factors for a user's choice of movie. Suppose also that a new user has joined the movie subscription service, and has rated some, but not all, of the movies. To predict how this new user will rate other movies (and thus, to determine which ones to recommend), all movies the user has not watched are assigned the average rating for that movie given by all users to form a new matrix A' E M(m+1)xn(R), and the rank-10 approximation of A' is computed from its SVD. The values in the approximation to A' are taken as the predicted ratings for the new user. Given this procedure, which of the following conclusions is most correct?
