```A little insight from Dr. Larrie Ferreiro from SEOR.

FYI, the average of the all guesses for each jar were:

Jar 1: 176 (actual 168, within 5%)

Jar 2: 157 (actual 148, within 6%)

Jar 3: 175 (actual 229, within 30%)

Two-thirds of the jar guesses verify Galton's theory popularized in the Wisdom of Crowds), that the average guess is more accurate the most individual guesses

Subject: Results of the Fall Candy Guessing Contest

Good Morning Everyone,

The results are in for the Candy Guessing Contest.......

The winner of Jar #1 is Susan Brionez with a guess of 175 when the jar actually contained 168 candies.

The winners of Jar #2 are Richard Carver and Terri Mancini. Both guessed the exact number of candies in the jar (148).

The winner of Jar #3 is Suzie Mueller with a guess of 234 when the jar actually contained 229 candies.

The winners can come up to the Dean's Suite 5100 to collect their prize of the candy, jar and a gift card.

Looking at these guesses, Bill Rosenberger might want to examine these entries for possible candidates for his STAT 250 class. :)
