About 42.3% of Californians and 19.6% of all Americans over age five speak a language other than English at home. Using your class as a sample, conduct a hypothesis test to determine if the percent of the students at your school who speak a language other than English at home is different from 42.3% Ho=____ Ha=____ In words, define the random variable ___ =___ The distribution to use for the test is ____ Determine the test statistic using your data Draw a graph and label it appropriately. Shade the actual level of significance
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.
