Os#3Microsoft Word -...You are conducting a study to see if the proportion of voters who prefer the Democratic candidate issignificantly different from 62% at a level of significance of a = 0.05. According to your sample, 27 out of50 potential voters prefer the Democratic candidate.Ea. For this study, we should use [z-test for a population proportionb. The null and alternative hypotheses would be:Ho: p=✓0.62(please enter a decimal)H₁: p(Please enter a decimal)c. The test statistic z = -1.165 (please show your answer to 3 decimal places.)(Please show your answer to 4 decimal places.)d. The p-value = Ïe. The p-value is ? af. Based on this, we should Select an answer the null hypothesis.g. Thus, the final conclusion is that ...80F3O The data suggest the populaton proportion is significantly different from 62% at a = 0.05, sothere is sufficient evidence to conclude that the proportion of voters who prefer theDemocratic candidate is different from 62%O The data suggest the population proportion is not significantly different from 62% at a = 0.05,so there is sufficient evidence to conclude that the proportion of voters who prefer theDemocratic 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 theDemocratic candidate is different from 62%.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 candidatediffers from 62%.O There is a 24.38% chance of a Type I error.O If the sample proportion of voters who prefer the Democratic candidate is 53% and if another50 voters are surveyed then there would be a 24.38% chance that we would conclude eitherfewer than 62% of all voters prefer the Democratic candidate or more than 62% of all votersprefer the Democratic candidate.O If the population proportion of voters who prefer the Democratic candidate is 62% and ifanother 50 voters are surveyed then there would be a 24.38% chance that either fewer than53% of the 50 voters surveyed prefer the Democratic candidate or more than 71% of the 50voters surveyed prefer the Democratic candidate.i.
