Suppose that the editor of a new textbook was hoping that the book would have mean word length of 6.5 letters. The editor randomly selected 20 words from randomly selected pages. That data is given on the Data Set page for "Word Count". Find the probability that the mean word length of the textbook differs from the desired 6.5 letters by more than 1. Correctly round your percentage to 2 decimal places in your conclusion sentence. Word count: 5,5,2,11,1,5,3,8,5,4,7,2,9,4,8,10,4,5,6,6 * Trying to calculate z-score and probabilty.
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.
