To find the mean of the original dataset, we add all the ages together and divide by the total number of individuals:
Mean of original dataset = (24 + 15 + 18 + 30 + 32 + 40 + 22 + 27 + 33 + 35) / 10
= 296 / 10
= 29.6 years
Now, to find the mean of the new dataset, we replace the maximum age (40) with 50 and find the mean using the same method:
Mean of new dataset = (24 + 15 + 18 + 30 + 32 + 50 + 22 + 27 + 33 + 35) / 10
= 286 / 10
= 28.6 years
The mean of the new dataset is 28.6 years.
The difference between the mean of the new dataset and the mean of the original dataset is:
29.6 - 28.6 = 1 year
Therefore, the mean of the new dataset is 1 year higher than the mean of the original dataset.
