Is this normality requirement satsified in this case? no yes Give the 90% confidence interval for the population proportion: < p < To reduce the margin of error, we decide to use an 87% confidence interval for the population proportion. Give the 87% confidence interval: < p <
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.
At Wakanda Diner, adults over the age of 55 recieve a 25% discount. In a recent study, 79 out of 386 randomly selected adult diners admitted that they have lied about their age at least once in order to receive the discount. We wish to estimate the population proportion of all diners who have lied about their age using a 90% confidence interval. Round all answers to three decimal places when appropriate.
