06:23 A myopenmath.com You are conducting a study to see if the proportion of voters who prefer the Democratic candidate is significantly smaller than 55% at a level of significance of a = 0.10. According to your sample, 49 out of 92 potential voters prefer the Democratic candidate. a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ? 0 Select an answer > (please enter a decimal) H1: ? 0 Select an answer (Please enter a decimal) c. The test statistic ? 0 | (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 ? O a f. Based on this, we should Select an answer o the null hypothesis. g. Thus, the final conclusion is that ... The data suggest the populaton proportion is significantly smaller than 55% at a = 0.10, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is smaller than 55% The data suggest the population proportion is not significantly smaller than 55% at a = 0.10, so there is not sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is smaller than 55%. The data suggest the population proportion is not significantly smaller than 55% at a = 0.10, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is equal to 55%. h. Interpret the p-value in the context of the study. There is a 55% chance of a Type I error. If the population proportion of voters who prefer the Democratic candidate is 55% and if another 92 voters are surveyed then there would be a 36.87% chance fewer than 53% of the 92 voters surveyed prefer the Democratic candidate. If the sample proportion of voters who prefer the Democratic candidate is 53% and if another 92 voters are surveyed then there would be a 36.87% chance of concluding that fewer than 55% of all voters surveyed prefer the Democratic candidate. There is a 36.87% chance that fewer than 55% of all voters prefer the Democratic candidate. i. Interpret the level of significance in the context of the study.
