Suppose you have 40 college freshman who have volunteered to be part of this study. Design a completely randomized experiment that tests the hypothesis that hearing older students talk about overcoming challenges improves academic performance. Be sure your design addresses how randomization will be incorporated. (b) Suppose you have reason to believe that students with a history of strong academic performance respond differently than those with a history of modest performance. Outline a randomized block design using the same subjects that will address this difference.

me! what did you put for this question?

step-by-step explanation:

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
