The U.S. Dairy Industry wants to estimate the mean yearly milk consumption. A sample of 19 people reveals the mean yearly consumption to be 70 gallons with a standard deviation of 14 gallons. Assume the population distribution is normal. (Use t Distribution Table.) a-1. What is the value of the population mean? Unknown 70 14 a-2. What is the best estimate of this value? For a 98% confidence interval, what is the value of t? (Round your answer to 3 decimal places.)
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.
