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

Determine if the random variable from the experiment follows a Binomial Distribution.

An investor randomly purchases 10 stocks listed on a stock exchange. Historically, the probability that a stock listed on this exchange will increase in value over the course of a year is 46%. The number of stocks that increase in value is recorded.

1. There there are two mutually exclusive outcomes (success/failure). True or False?

2. Since a sample size of 10 is less than 5% of all stocks on the exchange, the trials are independent. True or False?

3. There is a fixed number of trials. True or False?

4. The probability of success is the same for each trial of the experiment. True or False?

5. The random variable follows a Binomial Distribution. True or False?

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.

cording to a job website, each job opening on average attracted 251 résumés in 2016. The job market improved in 2017 compared to 2016, which means that more people will likely be switching jobs but also fewer nemploved workers remain in the job market. To find out which trend is stronger, a random sample of 20 employers in a region was taken. Each employer reported how many résumés they received in 2017 for each b opening. Their answers are shown in the accompanying table. Using a = 0.10, complete parts a through d. Click the icon to view the data on résumés received, a. State the null and alternative hypotheses.

After careful research you observe that the number of hackers active on each day is a random variable Bin(3,0.5) distribution. If no hackers are active, the probability of the website failure is 0.15; If one hacker is active the probability of the website failure is 0.3; if two or more hackers are active the probability of the website failure is 0.5. You conclude that the total probability of website failure on a given day is two decimal place). Assuming there is a failure, the probability no hackers are active is (to (to two decimal places).
