Q10: A factory producing electric motors has 0.2% defective rate. A quality control inspector tests randomly selected motors from this product line. a) What is the probability that the first defective motor will be the sixth one tested? b) What is the probability that the first defective motor will be among the first six tested? c) What is the expected waiting time before the first defective motor is tested?
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.
