You are a process engineer for a company that manufactures widgets. A particular machine at your company has some downtime during the day on 30.1% of days. You decided to make some changes to how the machine is calibrated in an attempt to reduce downtime. After monitoring the machine for 315 days after your changes were implemented, you find that the machine had some downtime during the day on 25.1% of days. Conduct a hypothesis test to determine if the proportion of days that the machine has downtime has changed from before, with a= 0.10. Using this information, what is the test statistic in your analysis? Round intermediate calculations to four decimal places, and choose the closest choice to your answer.
