A news article that you read stated that 59% of voters prefer the Democratic candidate. You think that the actual percent is different. 120 of the 236 voters that you surveyed said that they prefer the Democratic candidate. What can be concluded at the 0.05 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: Select an answer (please enter a decimal) H,: VSelect an answerv (Please enter a decimal) c. The test statistic ? (please show your answer to 3 decimal places.) d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is ?Va f. Based on this, we should Select an answerv the null hypothesis. g. Thus, the final conclusion is that ... O The data suggest the population proportion is not significantly different 59% at a = 0.05, so there is not sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is different 59%. O The data suggest the population proportion is not significantly different 59% at a = 0.05, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is equal to 59%. O The data suggest the populaton proportion is significantly different 59% at a = 0.05, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is different 59% h. Interpret the p-value in the context of the study. O if the population proportion of voters who prefer the Democratic candidate is 59% and if another 236 voters are surveyed then there would be a 1.08% chance that either fewer than 51% of the 236 voters surveyed prefer the Democratic candidate or more than 67% of the 236 voters surveyed prefer the Democratic candidate. O f the sample proportion of voters who prefer the Democratic candidate is 51% and if another 236 voters are surveyed then there would be a 1.08% chance that we would conclude either fewer than 59% of all voters prefer the Democratic candidate or more than 59% of all voters prefer the Democratic candidate. O There is a 1.08% chance that the percent of all voters who prefer the Democratic candidate differs from 59%. O There is a 1.08% chance of a Type I error. i. Interpret the level of significance in the context of the study. O If the population proportion of voters who prefer the Democratic candidate is 59% and if another 236 voters are surveyed then there would be a 5% chance that we would end up falsely concluding that the proportion of voters who prefer the Democratic candidate is different 59% O There is a 5% chance that the proportion of voters who prefer the Democratic candidate is different 59%. O There is a 5% chance that the earth is flat and we never actually sent a man to the moon. O If the proportion of voters who prefer the Democratic candidate is different 59% and if another 236 voters are surveyed then there would be a 5% chance that we would end up falsely concluding that the proportion of voters who prefer the Democratic candidate is equal to 59%.

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.
