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

An executive is managing 3 projects. Consider the following experiment: For each project, observe whether it is completed on time. Let A_i be the event that the i^th project is completed on time, where i = 1, 2, 3.

1) Are the events A₁, A₂, and A₃ are independent? Why or Why not, or is more information needed to make a determination?

2) Are the events A₁, A₂, and A₃ are mutually exclusive? Why or Why not, or is more information needed to make a determination?

3) Suppose that each project will be completed on time with
probability 0.6, independently of the others. What is the probability that at least 2 of them will be completed on time?

What is the probability that a randomly selected student does not have a Microsoft product and does not have an Apple product (does not have either product).
In a sales effectiveness seminar, a group of sales representatives tried two approaches to selling a customer a new automobile: the aggressive approach and the passive approach. For 1160 customers, the following record was kept: Suppose a customer is selected at random from the 1160 participating customers. Let us use the following notation for events: A = aggressive approach, Pa = passive approach, S = sale, N = no sale. So, P(A) is the probability that an aggressive approach was used, and so on. (a) Compute P(S), P(S | A), and P(S | Pa). (Enter your answers as fractions.) Simplify the fraction if needed P(S) = ? P(S | A) = ? P(S | Pa) = 95/116 (b) Compute P(A and S) and P(Pa and S). (Enter your answers as fractions.) Simplify the fraction if needed P(A and S) = ? P(Pa and S) = 95/232 (c) Compute P(N) and P(N | A). (Enter your answers as fractions.) Simplify the fraction if needed
Consider the experiment: You ask someone two multiple-choice questions. Each question could be answered with Yes (Y), No (N), or Don't Know (D). (For example, if you ask someone these two questions, they could answer Yes to both of them, or Yes to the first one and Don't Know to the second one, etc.) Let A be the event that the person answers Yes to at least one question, and Let B be the event that the person answers No to the second question. How many elements are in the sample space? What elements are in A ∩ B? What elements are in A ′?
This is a Statistics problem. Please explain each step thoroughly.

Finally, show that AA, BB, and CC are not mutually independent.

Practice question #7. A company has 3 assembly lines for making components: A1 is the event that a component is made on the first assembly line, A2 is the event a component is on the second line, and A3 is the event a component is on the third line.

Tina Fey goes trick-or-treating the night of Halloween dressed as Sarah Palin. She visits homes in her neighborhood to collect candy, but only receives candy, naturally, when the door is answered and the family still has a piece of candy to give away. Upon knocking, the probability of the door being answered is 3/4, and the probability that the home still has candy is 2/3. Assume that the events “Door answered” and “candy remaining” are independent and also that the outcomes at each home are independent. Also assume that each home gives away at most a single piece of candy. (c) Determine the probability that she receives her second piece of candy at the fifth house. (d) Given that she did not receive her second piece of candy at the second house(not sure if she receive her first candy), determine the conditional probability that she will receive her second piece of candy at the fifth house.
