Problem #19: An experiment is carried out to estimate the mean lifetime of tires manufactured with embedded steel particles. Testing of a random sample of 40 such tires gives a mean tire life of 97395 km, until the tread indicators are visible, with a sample standard deviation of 2876 km. An engineering student then gives her supervisor the confidence interval [96223.68, 98566.32] for the population mean tire life. What is the confidence level of this interval?

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.
