A used car dealer says that the mean price of a 2018 Honda Pilot LX is at least $23,900. You suspect this claim is incorrect and find that a random sample of 14 similar vehicles has the following costs. Is there enough evidence to reject the dealer's claim at a = 0.05? Assume the population is normally distributed. Data for prices of 14 Honda Pilot LXs. S21,200 $22,700 $24,000 S21,500 S22,900 $24,100 $21,700 $23,200 $24,300 $22,000 $23,500 $24,700 $22,500 S23,700 Identify the claim. Then state the null and alternative hypotheses. Use the t– test. Sketch a graph. Interpret the decision in the context of the original claim.

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.
