Suppose that the population of middle-school children has a mean of 350 on a reading test and σ = 50. Assume normality. What is the probability that a mean will be greater than 370 with a sample of 25 students? Leave the probability in decimal form (do not convert to percentage). Round to the nearest ten thousandth. (4 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.
