The average lifespan of a CleanFreek dishwasher is normally distrubuted with a mean of 9 years and a standerd deviation of 1.5 years . i.) What is the probablity that a Cleanfreek dishwasher will last longer than 10 years ? ii.) what is the probability that a cleanfreek dishwasher will last fewer than 6 years? iii.) What length warranty should be established on the dishwasher so that no more than 1.5% of the units will need to be replaced under warranty?
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.
