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}

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
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.
