Imagine you work as a maintenance manager for a company that sells large industrial machines. Before you took your position, 8.2% of machines required a repair after one year. After taking your position, you instituted changes to the maintenance procedure. You sample 303 machines after your changes were implemented, and find that 6.2% required repair after one year. Conduct a hypothesis test to determine if the proportion of machines that require repair after one year has decreased, with O= 0.01. Using this information, what is the test statistic in your analysis? Round intermediate calculations to four decimal places, and final answers to two decimal places
