Perform the appropriate Hypothesis Test (State the Null Hypothesis, Alternative Hypothesis, the appropriate test statistic, the p-value, whether you reject or fail to reject the null, and then interpret your conclusion): A simple random sample of 200 drivers were asked if they drive a car manufactured in a certain country. Of the 200 drivers surveyed, 107 responded that they did. Determine if more than half of all drivers drive a car made in this country. Use α=0.025.
