A graduating student keeps applying for jobs until she gets an offer. The probability of getting an offer at any trial is 0.35. a. What is the expected number of applications? What is the variance? b. If she has enough time to complete at most four applications, how confident can she be of getting an offer within the available time? c. If she wants to be at least 95% confident of getting an offer, how many applications should she prepare? d. Suppose she has time for at most four applications. For what minimum value of p can she have 95% confidence of getting an offer within the available time?
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.
