PLEASE HELP ASAP!!! I dont understand how they want me to do this. could someone please explain how to do it along with the answer?

Use the data given below to answer the following questions.

68, 63, 67, 66, 65, 87, 69, 61, 86, 82, 28.

A. What is the outlier of the data? Explain why you consider this number the outlier.

B. Calculate the mean of the given data set. You must show your work to receive all possible points.

C. Calculate the mean of the given data set excluding the outlier value. You must show your work to receive all possible points.

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
