You are conducting a study to see if the proportion of voters who prefer Candidate A is significantly smaller than 65% at a significance level
You are conducting a study to see if the proportion of voters who prefer Candidate A is significantly smaller than 65% at a significance level of = 0.025. According to your sample, 41 out of 69 potential voters prefer Candidate A.
- For this study, we should use Select an answer Chi-Square Test for Independence Chi-Square Test for Goodness of Fit Two Independent Proportions Comparison Two Independent Sample Means Comparison Given Data Confidence Interval for a Population Mean Given Statistics Hypothesis Test for a Population Mean Given Data Hypothesis Test for a Population Mean Given Statistics Confidence Interval for a Population Proportion Hypothesis Test for a Population Proportion One-Way ANOVA Two Dependent Sample Means Comparison Given Data Confidence Interval for a Population Mean Given Data Two Independent Sample Means Comparison Given Statistics
- The null and alternative hypotheses would be: H0H0: ? p Select an answer = > < (please enter a decimal) H1H1: ? p Select an answer = < > (Please enter a decimal)
- The test statistic = (please show your answer to 3 decimal places.)
- The p-value = (Please show your answer to 4 decimal places.)
- The p-value is Select an answer less than (or equal to) greater than
- Based on this, we should Select an answer accept fail to reject reject the null hypothesis.
- As such, the final conclusion is that ...
- The sample data suggest that the population proportion is not significantly smaller than 65% at = 0.025, so there is not sufficient evidence to conclude that the proportion of voters who prefer Candidate A is smaller than 65%.
- The sample data suggest that the populaton proportion is significantly smaller than 65% at = 0.025, so there is sufficient evidence to conclude that the proportion of voters who prefer Candidate A is smaller than 65%
