If the outliers are not included, what is the mean of the data set?

72, 82, 3, 55, 62, 73, 90, 80, 151, 59, 46, 31

59 65 67 73

mean will be 67

Step-by-step explanation:

We have given the numbers 72,82,3,55,62,73,90,80,151,59,46,31

We have to find the mean

Here total count of numbers = 12

Sum of total numbers = 72+82+3+55+62+73+90+80+151+59+46+31 = 804

We know that mean is given by

So mean will be 67

the answer   is 200

step-by-step explanation:

this is a problem about poisson probabilities.   i don't know if you've

already studied poisson distributions, or if you have a place to look

to read more about the subject.  

here's how you can see a poisson distribution coming.   when there are

a lot of events that may happen at any time (or any place), and when

you're counting how many of them happen at a particular time (or a

particular place), and each event is independent of the others, then

the result is a poisson distribution.   this is roughly true for the

chocolate chips; one chip being in a cookie has only a small effect on

the probability that another chip will be in the cookie.

once you know you have a poisson distribution, you know a lot.   there

is only one parameter to a poisson distribution, so if you know the

mean, you know everything.   the form of the distribution is

  probability of n chips = {[e^(-x)]*(x^n)} / (n! )

first, let's see what the pattern is.

58 - x = 47

46 - x = 36

x = 9

so this means that the term after 25 is 25 - 9:

the next term in the sequence is 16.
