An advertiser is experimenting with a new color scheme and conducts a study to test its effectiveness. In which situation could they use the two-sample t-test for comparing two population means?

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

c 1 hour

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e

if x = 1, then the answer is 3.5

you can't solve x because it is 2 linear equation and you only have one equation
