Would you say that most people can be trusted? A random sample of n1 = 250 people ages 18-25 showed that n = 45 said yes. Another random sample of n2 = 280 people ages 35-45 showed that r2 = 71 said yes. a) (i) Find 95% confidence interval for på – p2- Conduct hypothesis test at 5% significance level, do you have enough evidence to conclude that the population proportion of trusting people is higher for the older group? (ii)

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.
