The manufacturer of the X-15 steel-belted radlal truck tire clalms that the mean mileage the tire can be driven before the tread wears out Is 60,000 mlles. Assume the mileage wear follows the normal distributlon and the standard devl- ation of the distributlon is 5,000 mlles. Crosset Truck Company bought 48 tires and found that the mean mlleage for Its trucks Is 59,500 mlles. Is Crosset's experl- ence different from that clalmed by the manufacturer at tha 05 slanlficance lovel?

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.
