### Understanding Probabilities in Real-World Scenarios#### Question from Probability and StatisticsAccording to a 2020 article, 69% of men do not wash their hands after using a public restroom. Suppose a random sample of 40 men are selected. What is the probability that at least 30 of them will not wash their hands after using a public restroom?#### Answer Choices:- A. 0.161- B. 0.738- C. 0.839- D. 0.262In this problem, you are essentially dealing with a binomial probability question where you must determine if the occurrence of men not washing their hands matches the given criteria.1. **Population Parameter**: 69% (0.69) of men do not wash their hands.2. **Sample Size**: 40 men.3. **Desired Outcome**: At least 30 men do not wash their hands.To solve this, you may need to utilize binomial probability formulas or normal approximations (depending on your course or tool). The multiple-choice options suggest different probabilities, and calculating the exact probability will guide you to the correct answer. This type of problem helps students understand how probability theory is applied to real-world data and decisions. Through this example, learners can see the importance of source data and statistical methods in deriving meaningful conclusions.

Concept explainers

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.
