Answer:
C
Step-by-step explanatio
33 + 33 + 38 + 35 +37 + 40 + 57 = 273
273 / 7 = 39
33 + 33 + 38 + 35 +37 + 40 = 216
216 / 6 = 36
Final answer:
The mean (average) of the data set without the outlier is 36 and including the outlier is 39. The outlier here being the value 57 which deviates most from the other values in data set.
Explanation:
To find the mean (or average) of a data set, you add all the values together and then divide by the count of the values.
Firstly, for the mean without the outlier, we add 33+33+38+35+37+40 = 216, which we then divide by the 6 values, giving us 36. So, the mean without considering the outlier is 36.
For the mean considering all values including the outlier (57), calculate 33+33+38+35+57+37+40 = 273, then divide by the 7 values, which gives us approximately 39. The answer to the nearest tenth is 39.0. Therefore, the mean of this data set with the outlier is 39.0 and without the outlier is 36.0.
