Question

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?

  1. 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 
  2. 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 < ≠ > =  

  1. The test statistic ? z t  =  (round to 3 decimal places)
  2. The p-value =  (round to 4 decimal places)
  3. The p-value is ? > ≤  αα.
  4. Based on this, we should Select an answer accept reject fail to reject  the null hypothesis.
  5. Explain in your own words what you can conclude from this hypothesis test.
