Answer
GPT 3.5
To find the interval that represents the middle 68% of the scores, we need to look at one standard deviation above and below the mean.

68% of the scores fall within one standard deviation of the mean according to the empirical rule.
So, the middle 68% of Bella's scores would fall between 157 and 183.

Therefore, the interval that represents the middle 68% of the scores is 157 to 183.
