Question
You are conducting a study to see if the proportion of voters who prefer the Democratic candidate is significantly larger than 73% at a level of significance of αα = 0.01. According to your sample, 56 out of 75 potential voters prefer the Democratic candidate.
- For this study, we should use Select an answer z-test for a population proportion t-test for a population mean
- The null and alternative hypotheses would be:
Ho: ? p μ Select an answer < = ≠ > (please enter a decimal)
H1: ? p μ Select an answer ≠ < = > (Please enter a decimal)
- The test statistic ? z t = (please show your answer to 2 decimal places.)
- The p-value = (Please show your answer to 4 decimal places.)
- The p-value is ? ≤ > α
