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.

Definition Definition Method in statistics by which an observation’s uncertainty can be quantified. The main use of interval estimating is for describing a range that is made by transforming a point estimate by determining the range of values, or interval within which the population parameter is likely to fall. This range helps in measuring its precision.

In a study of 354,079 cell phone users, it was found that 139 developed cancer of the brain or nervous system. Assuming that cell phones have no effect, there is a 0.000469 probability of a person developing cancer of the brain or nervous system. We therefore expect about 167 cases of such cancer in a group of 354,079 people. Estimate the probability of 139 or fewer cases of such cancer in a group of 354,079 people. What do these results suggest about media reports that cell phones cause cancer of the brain or nervous system? (a) P(x s139) = | (Round to four decimal places as needed.) %3D

What do these results suggest about media reports that cell phones cause cancer of the brain or nervous system? (a) P(xs 26) = (Round to four decimal places as needed.) (b) What does the result from part (a) suggest about the media reports? O A.
