A news article that you read stated that 52% of voters prefer the Democratic candidate. You think that the actual percent is smaller. 103 of the 235 voters that you surveyed said that they prefer the Democratic candidate. What can be concluded at the 0.05 level of significance? a.

A news article that you read stated that 52% of voters prefer the Democratic candidate. You think that the actual percent is smaller. 103 of the 235 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 H₁: ? Select an answer c. The test statistic ? d. The p-value = e. The p-value is ? ✔a f. Based on this, we should g. Thus, the final conclusion is that ... = (please enter a decimal) (Please enter a decimal) (please show your answer to 3 decimal places.) (Please show your answer to 4 decimal places.) Select an answer the null hypothesis. O The data suggest the populaton proportion is significantly smaller 52% at a = 0.05, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is smaller 52% The data suggest the population proportion is not significantly smaller 52% at x = 0.05, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is equal to 52%. The data suggest the population proportion is not significantly smaller 52% at a = 0.05, so there is not sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is smaller 52%. h. Interpret the p-value in the context of the study. O There is a 0.61% chance that fewer than 52% of all voters prefer the Democratic candidate. If the sample proportion of voters who prefer the Democratic candidate is 44% and if another 235 voters are surveyed then there would be a 0.61% chance of concluding that fewer than 52% of all voters surveyed prefer the Democratic candidate. There is a 52% chance of a Type I error. O If the population proportion of voters who prefer the Democratic candidate is 52% and if another 235 voters are surveyed then there would be a 0.61% chance fewer than 44% of the 235 voters surveyed prefer the Democratic candidate. i. Interpret the level of significance in the context of the study. O There is a 5% chance that the proportion of voters who prefer the Democratic candidate is smaller 52%.

O If the population proportion of voters who prefer the Democratic candidate is 52% and if another 235 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 smaller 52% O If the proportion of voters who prefer the Democratic candidate is smaller 52% and if another 235 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 52%.

Expert Solution
Step 1: Given

Population proportion(P)=52%=0.52

Sample proportionopen parentheses P with hat on top close parenthesesequals 103 over 235 equals 0.4383
