3:45 wouldn't it be less than or equal to 7.5 rather than less than 7.5

hey sir! Apparently in my cgp aqa maths book, they mentioned that when 'n' is large, the approximation is accurate enough without needing to apply a continuity correction. I'm not sure if this applies to the other specs but I don't know if this info is real, even if it's from a respectable brand. Could you check if a continuity correction is needed for aqa exam this year?

So in other words the continuity corrections are just upper and lower bounds for each integer value?

1:57 Shouldn't it be 2.5 is less than or equal to x, not just less than? Or does that not matter.

What if the discrete data says p(x=7.5)??? Would I have (7, 8) as the boundaries?
