A study wanted to see if sunlight would help a cut heal better. They paid college students to volunteer, and the volunteers were random from all over campus. Each volunteer got a cut on their arm. Half the volunteers were instructed to get at least 20 hours of sunlight on the cut for the next week. The other half of the volunteers were instructed to avoid sunlight and get no more than ten minutes of sunlight on the cut. In the end they compared how well the cuts had healed in each group. This scenario is NOT a matched pairs experiment. Let's say we wanted to do a matched pairs experiment with the SAME set of volunteers. How could we change this story to be matched pairs

step-by-step explanation:

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
