- For this study, we should use Select an answer t-test for a population mean z-test for a population proportion Correct
- The null and alternative hypotheses would be:
H0:H0: ? p μ Correct Select an answer ≠ < > = Correct (please enter a decimal)
H1:H1: ? p μ Correct Select an answer > = < ≠ Correct (Please enter a decimal)
- The test statistic ? t z Correct = (please show your answer to 3 decimal places.)
- The p-value = (Please show your answer to 4 decimal places.)
The study is about voter participation decline for the upcoming election indicating that the appropriate test is z-test for a population proportion.
Correct Answer: z-test for a population proportion.
It is clear that 18% of registered voters voted in the last election. The hypothesis is,
Null hypothesis:
Alternative hypothesis:
The sample proportion is,
The sample proportion is 0.1713.
