The US Department of Energy reported that 49% of homes were heated by natural gas. A random sample of 328 homes in Oregon found that 174 were heated by natural gas. Test the claim that proportion of homes in Oregon that were heated by natural gas is different than what was reported. Use a 1% significance level. Give answer to at least 4 decimal places. What are the correct hypotheses? (Select the correct symbols and use decimal values not percentages.) Họ: Select an answer ♥ Ha: [Select an answer Based on the hypotheses, find the following: Test Statistic = p-value = Based on the above we choose to Select an answer The correct summary would be: [ Select an answer homes in Oregon that were heated by natural gas is different than what the DOE reported value of 49%. that the proportion of

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.
