A quality control engineer inspects a random sample of three batteries from a lot of 30 car batteries, which are ready to be shipped. If such a lot contains ten batteries with slight defects, what then is the probability that the inspector’s sample contains i. No batteries with slight defects? ii.At least one of the batteries with slight defects? Engineering Subject= Applied Statistic
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.
