Find the mean absolute deviation of 34,12,49,8,2

Mean Absolute Deviation: 16.4

Step-by-step explanation:

Mean: 2 + 8 + 12 + 34 + 49 = 105/5 = 21

21 - 2 = 19

21 - 8 = 13

21 - 12 = 9

21 - 34 = 13

21 - 49 = 28

Mean Absolute Deviation: 9 + 13 + 13 + 19 + 28 = 82/5 = 16.4

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
