Looking to solve for test statistic and p value

Question 8 of 9 0.83 / 1 . . . View Policies Show Attempt History Current Attempt in Progress Football Air Pressure During the National Football League's 2014 AFC championship game, officials measured the air pressure on 1 1 of the game footballs being used by the New England Patriots. They found that the balls had an average air pressure of 1 1. 1 psi, with a standard deviation of 0.40 psi. Assuming this is a representative sample of all footballs used by the Patriots in the 2014 season, perform the appropriate test to determine if the average air pressure in footballs used by the Patriots was significantly less than the allowable limit of 12.5 psi. There is no extreme skewness or outliers in the data, so it is appropriate to use the t-distribution. Pa
