The marketing manager for an automobile manufacturer is interested in determining the proportion of new compact-car owners who would have purchased a GPS navigation system if it had been available for an additional cost of $300. The manager believes from previous information that the proportion is 0.30. Suppose that a survey of 200 new compact-car owners is selected and 79 indicate that they would have purchased the GPS navigation system. What is the test statistic value if you were to conduct a test to determine whether there is evidence that the proportion is different from 0.30 at the 0.05 level of significance?
Let 20.05 1.65; 20.025 = 1.96
