A leading magazine (like Barron's) reported at one time that the average number of weeks an individual is unemployed is 29.3 weeks. Assume that for the population of all unemployed individuals the population mean length of unemployment is 29.3 weeks and that the population standard deviation is 7.5 weeks. Suppose you would like to select a random sample of 84 unemployed individuals for a follow-up study. Find the probability that a single randomly selected value is between 27.7 and 30.9. P(27.7 < X < 30.9) = Find the probability that a sample of size n = 84 is randomly selected with a mean between 27.7 and 30.9. P(27.7 < T < 30.9) = Enter your answers as numbers accurate to 4 decimal places.

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.
