You hear a lot of talk about increasing global temperature, so you decide to see for yourself if there has been an actual change in recent years. You know that the average land temperature from 1951-1980 was 8.79 degrees Celsius. You find annual average temperature data from 1981-2017 and decide to construct a 99% confidence interval (because you want to be as sure as possible and look for differences in both directions, not just one) using this data to test for a difference from the previous average.

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.

Transcribed Image Text:You hear a lot of talk about increasing global temperature, so you decide to
see for yourself if there has been an actual change in recent years. You know
that the average land temperature from 1951-1980 was 8.79 degrees Celsius.
You find annual average temperature data from 1981-2017 and decide to
construct a 99% confidence interval (because you want to be as sure as
possible and look for differences in both directions, not just one) using this
data to test for a difference from the previous average.
