Jeff Wilke says that one of the most important things an experimenter should do when setting up a hypothesis test is write down explicitly the control and treatment. What are the control and treatment for Amazon’s shopping cart A/B test?

Please see attachment for co troll and treatment for amazon

idk bring the function back   im not smart

step-by-step explanation:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
