    COVID

    I think the term covid should be banned now. It literally has been reduced to a flu in 2024 cause everyone's already immune to it. Only libtards still exploit this word to make everyone stay home and wear masks. I doubt you will even spread the disease if you go since everyone has gotten it...

    one of the solutions said "iqr is too small for D" but that boxplot isn't even to scale. I think they just wanted to show you that it was normally distributed

    Surely question 8 is C right? Cause the boxplot can look like that, but for C, it's multimodal.
