In a survey of 35 students at a local high school, 16 support changing the school's mascot. Find the 99%99% confidence interval for the true population proportion of students who support changing school's mascot. Choose the correct confidence interval and critical value used in the calculation. (0.237,0.677) (Zc=2.576) (0.257,0.657) (Zc=2.326) (0.317,0.597)) (Zc=1.645) (0.347,0.567)(Zc=1.282) (0.227,0.687) (tc=2.7284)
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.
