f. Based on this, we should reject g. Thus, the final conclusion is that ... X the null hypothesis. X O The data suggest the populaton proportion is significantly different from 62% at a = 0.05, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is different from 62% The data suggest the population proportion is not significantly different from 62% at x = 0.05, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is equal to 62%. O The data suggest the population proportion is not significantly different from 62% at a = 0.05, so there is not sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is different from 62%. X h. Interpret the p-value in the context of the study. O There is a 24.38% chance that the percent of all voters who prefer the Democratic candidate differs from 62%. O There is a 24.38% chance of a Type I error. If the sample proportion of voters who prefer the Democratic candidate is 53% and if another 50 voters are surveyed then there would be a 24.38% chance that we would conclude either fewer than 62% of all voters prefer the Democratic candidate or more than 62% of all voters prefer the Democratic candidate. O If the population proportion of voters who prefer the Democratic candidate is 62% and if another 50 voters are surveyed then there would be a 24.38% chance that either fewer than 53% of the 50 voters surveyed prefer the Democratic candidate or more than 71% of the 50 voters surveyed prefer the Democratic candidate.
