a. the mean is nothing . ​(type an integer or decimal rounded to one decimal place as​ needed.)
b. the data set does not have a mean.

Answer 1

Ok, so when finding the mean the first step you want to do is...
add all the numbers together then divide it by the amount of numbers 
example:
 5+5= 10
There are 2 numbers in the equation so then you will divide the sum by the amount. So the mean would be 5. Hope this helped!!!!
