Using Statistics to Describe
be Data
Assume this is a positive ordered set of data. Which statistics show values that would most likely describe the
following set of data? X, 9, 11, 13, Y, 20
Range = 17
Describe the data
Do not describe the data
Median = 10
Mean = 12
Range = 23
Interquartile range = 7
Interquartile range = 12
Done

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

it would rotate about 180 degrees.
