Answer:

the answers C just did this question!!:)

Step-by-step explanation:

The mean of the new data set = 240.1

The mean of the 6 outliers = 688

Total value of the outliers = 688 x 6 = 4128

The mean of the 100 observations = 267

Total value of the 100 observations = 267 x 100 = 26700

The total value of the new data set = 26700 - 4128 = 22572

Total number of new data set = 100 - 6 = 94

Mean of the new data set = 22572/94

Mean of the new data set = 240.1

The mean of the new data set = 240.1
