Consider the scenario where performance of two models (A and B) are measured on the same cross validation folds. To evaluate a hypothesis that the average performance of model A is better than the average performance of model B, what type of hypothesis test should you use? Unpaired, two-sided t-test
Paired, two-sided t-test
Paired, one-sided t-test
Unpaired, one-sided t-test

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.
