The number ofhours anent in an airplane on a single flight is recorded on a dot plot.

The mean is 5 hours and the standard devition is approximately 5.82 hours. The
median is 4 hours and the IQR is 3 hours. The value 26 hours is an outier that should not have been included in the data.

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
