Suppose you want to test the claim that a population mean equals 33. (a) State the null hypothesis. (b) State the alternate hypothesis if you have no information regarding how the population mean might differ from 33. (c) State the altermative hypothesis if you believe (based on experience or past studies) that the population mean may exceed 33. (d) State the alternative hypothesis if you believe (based on exxperience or past stud es) that the population mean may be less than 33.

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.
