To investigate the fluid mechanics of swimming, twenty swimmers each swam a specified distance in a water-filled pool and in a pool where the water was thickened with food grade guar gum to create a syrup-like consistency. Velocity, in meters per second, was recorded and the results are given in the table below. Velocity (m/s) Water Guar Syrup Swimmer - M₂² M₂-0 ⒸM₂ M₂=O M 1 ⒸM₂₂ 2 3 7 7 ⒸM₂₂-0 7 9 10 12 13 15 16 B M₂ M₂ O ⒸM₂ MO 18 19 20 0.90 1.00 1.10 1.20 1.25 1.35 1.40 1.40 1.50 1.65 1.70 1.75 Lis 1.80 1.85 1.90 1.95 0.91 0.98 0.95 1.21 1.21 1.28 1.30 1.34 1.42 The researchers concluded that swimming in guar syrup does not change mean swimming speed.

The data provide convincing evidence that swimming in guar syrup changes mean swimming speed We reject M. The data do not provide convincing evidence that swimming in guar syrup changes mean swimming speed. We fall to reject M. The data do not provide convincing evidence that swimming in guar syrup changes mean swimming speed. We reject M₂. The data provide convincing evidence that swimming in guar syrup changes mean swimming speed.
