What is a Paired T Test (Paired Samples T Test / Dependent Samples T Test)?

Imagine you designed two classification algorithms, labeled A and B. The table below shows the accuracy that was observed for 10-fold cross-validation. Using a paired t-test, can you determine whether the performance differences are statistically similar? Extremely statistically similar? show all of your work.

A B
73 93
81 83
82 83
72 90
85 89
86 78
87 93
89 90
93 95
81 90

Assume Alpha Level is 0.05 (5%)
