Computer hard drives must rotate in a balanced way and away from level is called pitch. Samples are taken regularly from production and each disk in the sample is placed in test equipment that results in a pitch measurement. From various samples it is concluded that the population is normal. The variance = image 1 when the process is in control. A sample of 10 is collected each week. The process will be declared out of control if the sample variance exceeds 0.122 What is the probability that it is declared out of control even when variance = image 1?
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.
