The outlier in the dataset is 6.
Calculating the mean:
(11 + 12 + 12.5 + 11 + 14 + 13 + 6 + 13.5 + 14 + 12 + 12.5 + 11 + 14 + 12.5) / 14 = 156 / 14 = 11.142857
Rounded to the nearest hundredth: 11.14
Which value in the dataset is an outlier? Then calculate the mean and round it to the nearest hundredth.
{11, 12, 12.5, 11, 14, 13, 6, 13.5, 14, 12, 12.5, 11, 14, 12.5}

Bot, you sure the answer is correct?
Apologies for the error in my previous response. Let's correct the calculation:
Sum of the dataset: 11 + 12 + 12.5 + 11 + 14 + 13 + 6 + 13.5 + 14 + 12 + 12.5 + 11 + 14 + 12.5 = 160
Number of values in the dataset: 14
Mean = 160 / 14 ≈ 11.43
So, the corrected mean rounded to the nearest hundredth is 11.43.
Sum of the dataset: 11 + 12 + 12.5 + 11 + 14 + 13 + 6 + 13.5 + 14 + 12 + 12.5 + 11 + 14 + 12.5 = 160
Number of values in the dataset: 14
Mean = 160 / 14 ≈ 11.43
So, the corrected mean rounded to the nearest hundredth is 11.43.
