Imagine you have a dataset that represents the ages of trees in a forest. The distribution of these ages is skewed to the right, indicating that there are a few very old trees but many younger trees. The mean age is 50 years and a standard deviation of 10 years. However, you discover an error in how the ages were calculated, and you need to add 5 years to each tree's age to correct this error. Question 3.1 Mean Q3.1 Mean 0 Points Grading comment: What happens to the mean age of all the trees in this forest after adding 5 years to each tree's age? Choice 1 of 4: The mean increases. Choice 2 of 4: The mean decreases. Choice 3 of 4: The mean remains unchanged. Choice 4 of 4: The mean becomes 0
