The television show September Road has been successful for many years. That show recently had a share of 31, which means, that among the TV sets in use, 31% were tuned to September Road. An advertiser wants to verify that 31% share value by conducting its own survey, and a pilot survey begins with 10 households have TV sets in use at the time of a September Road broadcast. Find the probability that none of the households are tuned to September Road. P(none) = Find the probability that at least one household is tuned to September Road. P(at least one) = Find the probability that at most one household is tuned to September Road. P(at most one) = %3D If at most one household is tuned to September Road, does it appear that the 31% share value is wrong? (Hint: Is the occurrence of at most one household tuned to September Road unusual?) yes, it is wrong no, it is not wrong

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.
