QUESTION 1 To estimate the average time it takes to assemble a certain computer component, the industrial engineer at an electronics firm timed 9 technicians in the performance of this task, getting a mean of 12.2 minutes and a standard deviation of 1.9 minutes. Construct a 9596 confidence interval of the actual average time required to do the job assuming that the actual time follows a normal distribution. O (11.158, 13.242) O (10.740, 13.660) (11.022. 13.378) O (10.959, 13.441)

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.
