I did maths A-level but with no statistics units so have no idea what I'm doing.
I am testing pyrotechnics to see if they function correctly as part of my gap year. I need to know if I can be 95% certain that there is a significant difference between two groups of data. The first group, A, contains 118 data points and the second, B, contains 14 data points. In group A, 1 of the 118 tests failed. In group B, 2 of the 14 tests failed.
Is there a way to test the significance of this difference?
