Suppose we wish to test a hypothesis about the differences in true means based on the condition that both samples n1 and n2 are > 30 and are randomly and independently drawn from populations with known variances. Under what condition is the null hypothesis rejected?

understand that i don't know the answers

will someone answer his question

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )

step-by-step explanation:

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
