Question

A news article that you read stated that 54% of voters prefer the Democratic candidate. You think that the actual percent is larger. 157 of the 249 voters that you surveyed said that they prefer the Democratic candidate. What can be concluded at the 0.01 level of significance?

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:
Ho: ? p μ Correct Select an answer ≠ > < = (please enter a decimal)
H₁: ? μ p Correct Select an answer > < = ≠ (Please enter a decimal)

The test statistic ? z t = (please show your answer to 3 decimal places.)
The p-value = (Please show your answer to 4 decimal places.)
The p-value is ? ≤ > αα
Based on this, we should Select an answer fail to reject accept reject the null hypothesis.
