The histogram above shows the results of a free throw contest held at the grand opening of a new sporting goods store. 81 people participated in the contest; each participant attempted 10 free throws. If 9 more people had entered the contest and each of them made 5 out of 10 free throws, how would the standard deviation of the data be different?
I made the correct choice based on the assumption that the more the new data made it appear more like a normal bell shape curve that would lower the standard deviation. My assumption was correct because nine more 5’s would make it look more bell shaped
