Suppose that Amazon has begun to test the use of drones for same-day delivery. If you wished to test:

H subscript O colon space sigma squared less or equal than 0.75
H subscript A colon space sigma squared greater than 0.75

and n = 20 home deliveries were included in the dataset, with a sample variance of 0.82, calculate the value of the Test Statistic (TS) that you would use to perform this test. Round off your answer to the third decimal place:

The TS, rounded off as instructed, is:
