Minh is a criminal justice researcher. He comes across several articles that demonstrate that communities that are supported in education, employment, healthcare, and childcare are associated with lower rates of crime. Minh convinces the city to conduct a study by investing in these areas hoping to reduce crime from the mean of 140 robberies/year. The null hypothesis would state that there would be no reduction (greater than or equal to 140): µ ≥ 140 robberies/year The alternative hypothesis would state that there would be a reduction: How would it be written?
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.
