It is a well-established fact that 40% of people are scared of squirrels. a- If we take a SRS of 50 people, find the probability that fewer than 38% of our sample are afraid of squirrels b- If we take a SRS of 250 people, find the probability that fewer than 38% of our sample are afraid of squirrels
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.
