Approximately 58% of all people are able to wink with both eyes. Is this percent different for people who wear glasses? A researcher tests 319 people who wear glasses and found that 204 could wink with both eyes. What can be concluded at the αα = 0.05 level of significance? For this study, we should use Select an answer z-test for the difference between two population proportions t-test for a population mean z-test for a population proportion t-test for the difference between two dependent population means t-test for the difference between two independent population means The null and alternative hypotheses would be: H0:H0: Select an answer μd p1 p μ1 μ Select an answer ≥ = ≠ ≤ H1:H1: Select an answer μ μ1 p p1 μd Select an answer < ≠ > = The test statistic ? z t = (round to 3 decimal places) The p-value = (round to 4 decimal places) The p-value is ? > ≤ αα. Based on this, we should Select an answer accept reject fail to reject the null hypothesis. Explain in your own words what you can conclude from this hypothesis test.

Approximately 58% of all people are able to wink with both eyes. Is this percent different for people who wear glasses? A researcher tests 319 people who wear glasses and found that 204 could wink with both eyes. What can be concluded at the αα = 0.05 level of significance?
- For this study, we should use Select an answer z-test for the difference between two population proportions t-test for a population mean z-test for a population proportion t-test for the difference between two dependent population means t-test for the difference between two independent population means
- The null and alternative hypotheses would be:
H0:H0: Select an answer μd p1 p μ1 μ Select an answer ≥ = ≠ ≤
H1:H1: Select an answer μ μ1 p p1 μd Select an answer < ≠ > =
- The test statistic ? z t = (round to 3 decimal places)
- The p-value = (round to 4 decimal places)
- The p-value is ? > ≤ αα.
- Based on this, we should Select an answer accept reject fail to reject the null hypothesis.
- Explain in your own words what you can conclude from this hypothesis test.
