Step-by-step explanation:
I’m pretty sure it’s the last one! :)
A null hypothesis is a statement where there is no association between the two groups you're talking about.
Say the first number is x, you would then have x and 6x and then x + 100. If you add all these together you get 8x + 100 = 708. You then subtract both sides by 100 and get 8x = 608. Divide both sides by 8 and you get 608/8 which = 76.
