Best ResponseYou've already chosen the best response.0Each one of the dots represents an amount of numbers in the set. So if a 60 had 2 dots on it, you would have 2 60's in the sequence. (60, 60, ... ) so continue doing that for all the numbers

Best ResponseYou've already chosen the best response.1xbar will be used in place of \(\Large \mu\) the standard deviation is \(\Large \sigma\)

Best ResponseYou've already chosen the best response.1what you need to do is compute 81.72  k*10.47259 for k = 1, k = 2, and k = 3 also compute 81.72 + k*10.47259 for k = 1, k = 2, and k = 3
