When the outlier is removed, the mean is approximately 15.27 hours.
In mathematics and statistics, the mean refers to the average of a set of numbers. It is calculated by adding up all the values in a dataset and then dividing the sum by the total number of values.
Original dataset without the outlier: 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 28
Now, calculate the mean:
Mean = (6 + 8 + 10 + 12 + 14 + 16 + 18 + 20 + 22 + 24 + 28) / 11
Mean = 168 / 11
Mean is approximately 15.27 hours.
Therefore, when the outlier is removed, the mean is approximately 15.27 hours.
The number of hours spent in an airplane on a single flight is recorded on a dot plot. The mean is 5 hours and the standard deviation is approximately 5.82 hours. The median is 4 hours and the IQR is 3 hours. The value 26 hours is an outlier that should not have been included in the data. 6 8 10 12 14 16 188 20 22 24 26 28 number of hours spent in an airplane When the outlier is removed from the data set
